After I upgraded to OS X 10.8, I recently upgraded my CMake version to 2.8.8.  

I can build CMake projects if I use "Unix Makefiles" as a generator, but if I use the Xcode generator, I get the following error:

The C compiler identification is GNU 4.2.1
The CXX compiler identification is GNU 4.2.1
Checking whether C compiler has -isysroot
Checking whether C compiler has -isysroot - yes
Checking whether C compiler supports OSX deployment target flag
Checking whether C compiler supports OSX deployment target flag - yes
Check for working C compiler using: Xcode
Check for working C compiler using: Xcode -- broken

CMake Error at /Developer/CMake 2.8-8.app/Contents/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:52 (MESSAGE):
The C compiler "/usr/bin/gcc" is not able to compile a simple test program.

It fails with the following output:

Change Dir: /Users/etuka/projects/baml/onethousand/build/CMakeFiles/CMakeTmp


Run Build Command:/Developer/CMake\ 2.8-8.app/Contents/bin/cmakexbuild
-project CMAKE_TRY_COMPILE.xcode build -target cmTryCompileExec3395723889
-buildstyle Development

xcodebuild: error: option '-buildstyle' is no longer supported

I understand that this error is associated with earlier versions of Cmake that are incompatible with Xcode 4.4.  I have tried removing all traces of CMake 2.8.8 that I can from my system and re-installing, but I cannot get rid of this error.  I would be grateful for suggestions of what to try next.

Thanks,
