1. What OS are you using (Brand and version - Ex. Windows XP SP3 or Windows 7 x64)?
mac book pro 10.6.8
2. What architecture is the OS you are running (x64 or x86)?
i dont understand what this is or how to check it
3. What version and architecture is your java install? (Type: java -version in command prompt.)
If you run any GNU/Linux, run this command to get all 3:
the version is 1.6.0

4. Are you running any wrappers? McMyAdmin, mcadmin, Hamachi, etc?
no
5. What build of CraftBukkit are you running? (do NOT say latest. Say the build number.)
The build number is displayed in the top of the server.log.
thats the really odd thing, i went to get craft bukkit and i will show the instructions below, but there isnt anything about downloading CraftBukkit, it just asks me to make a folder called craft bukkit and then follow what else it says. i will put the instructions im trying to follow below
Now that you've given us all the basics, now we get into the more advanced stuff. Note, if you haven't answered 1-5 yet, answering 6-10 will be almost pointless.

6. What command are you using to run your CraftBukkit server?
you mean like the command file? this
file://localhost/Users/cameronhill/Documents/cameronhill/Games/Minecraft%20Folder/Tekkit%20Hunger%20Games/Server/CraftBukkit/start_server.command
7. What plugins are you running?
none im just trying to get it all set up
8. What error are you getting (post your server.log file - pastebin.com or pastie.org please)?
The file “start_server.command” could not be executed because you do not have appropriate access privileges.
9. What have you tried already?
doing what the instructions say, i cant program and if the intructions dont work a lot of the times i have no idea how to problem solve it other than looking up the problem and posting on the forums
10. Have you tried any of the things below?

now that thats done, here are the instructions im trying to follow.


Mac OS X

1. Install Java
   Since OS X 10.7 Java does not come packaged with OS X. You will need to install java from the Apple's website http://support.apple.com/kb/DL1421
2. Obtaining the Server Files
   To run a server you will need the server jars, i.e. the server files. We will need a place to put the files.
   1. Create a New Folder
      Open up finder, and create a new folder in your Home folder named CraftBukkit
   2. Download the File
      Download the server files. You can download the latest builds from the front page of the wiki.
      Note: Download the stable build if you are not chasing the cutting edge in the development build
   3. Move the File
      Move the file from the Downloads folder to the CraftBukkit folder you created.
3. Obtaining startup script
   To easily start the server you will need a startup script. The following is a basic server script to start your server.
   1. Open up TextEdit set it to plan text mode under format and paste the following in
      #!/bin/bash
      cd "$( dirname "$0" )"
      java -Xmx1024M -Xms1024M -jar craftbukkit.jar -o true
   2. Save the file
      Save it in your CraftBukkit folder as start_server.command
   3. Allow the script to run
      1. Open up Terminal.app
      2. Type into Terminal.app
         chmod a+x
         Warning: Do not hit return
      3. drag the start_server.command into Terminal.app
      4. hit return
4. Starting the server
   From this point on you can start the server by double-clicking start_server.command.
   You will need to run the server once for it to generate some configuration files.
   Warning:
   To stop the server, do not close the terminal/command prompt window. Instead, type 'stop' into the console. Closing the terminal window without stopping the server could lead to corruption of the save files.
   
   
   
   
   
   thank you, please post a reply about what to do

Right click start_server.command, click Get Info, look at the Sharing and Permissions section at the very bottom and make sure you have Read & Write permissions.

yes, that was one of the first things i tried.

If all fails, sudo is the way to go. ^^

chmod +x <drag file here>
EDIT:
Its even says here:

yes, if thats what your asking i dragged it into the terminal,
whats sudo?

and also does anyone have an answere or something to say about the fact that in the whole process of getting bukkit running it didnt tell me to download a version?
