There's no reason why Android cannot be built on non-Ubuntu systems. Please send any success or failure reports to repo-discuss@googlegroups.com. In general you will need:

Mac OS

Requirements:

• To build the Android files in a Mac OS environment, you need an Intel/x86 machine. The Android build system and tools do not support the obsolete PowerPC architecture.
• Android must be built on a case-sensitive file system.
  
  • We recommend that you build Android on a partition that has been formatted with the "Case-sensitive Journaled HFS+" file system:
    • A case-sensitive file system is required because the sources contain files that differ only in case.
    • Journaled systems are more robust. (This is optional, but recommended.)
    • HFS+ is required to successfully build Mac OS applications such as the Android Emulator for OS X.
  • If you want to avoid partitioning/formatting your hard drive, you can use a case-sensitive disk image instead.
    • To create the image:
      
      • launch /Applications/Utilities/Disk Utility
      • select "New Image"
      • size: 8 GB (this will work, but you can choose more if you want to)
      • volume format: case sensitive, journaled
    • This will create a .dmg file which, once mounted, acts as a drive with the required formatting for Android development. For a disk image named "android.dmg" stored in your home directory, you can add the following to your ~/.bash_profile to mount the image when you execute "mountAndroid":
      
      
      # command to mount the android file image
      function mountAndroid { hdiutil attach ~/android.dmg -mountpoint /Volumes/android; }
      
      
      Once mounted, you'll do all your work in the "android" volume. You can eject it (unmount it) just like you would with an external drive.

1. Install the XCode version 2.4 or later from http://developer.apple.com . We recommend version 3.0 or newer.
   
2. Install MacPorts. To do this:
   1. Download the tar file from http://www.macports.org/ and untar the files.
   2. Run the following:
      $ ./configure
      $ make
      $ sudo make install
      $ sudo port selfupdate
   3. View your path:
      $ echo $PATH
      Make sure that /opt/local/bin is in your path before /usr/bin. If not, edit $HOME/.bash_profile and add the line "export PATH=/opt/local/bin:$PATH" (or the equivalent for other shells) after any other PATH-related lines. To verify that your path is now correct, open a new terminal and run echo $PATH again.
      
3. Upgrade GNU make to 3.81 or later by running
   $ sudo port install gmake
   $ sudo ln -s gmake /opt/local/bin/make
   
4. Install libsdl by running
   $ sudo port install libsdl
   
5. Set an appropriate per-process file descriptor limit. To do this, add the following lines to your .bash_profile file:
   # set the number of open files to be 1024
   ulimit -S -n 1024
6. Install Git and the GNU Privacy Guard:
   $ sudo port install git-core gnupg
   (You will need Git 1.5.4 or newer.)
   
7. Install these optional packages, if you want to:
   $ sudo port install xemacs +sumo
   $ sudo port install gimp
