破碎CMake和GCC下OS X(Broken CMake and GCC under OS X)

当运行configure中cmake-gui在我的OS X平台，我得到发生以下错误：

The C compiler identification is GNU
The CXX compiler identification is GNU
Checking whether C compiler has -isysroot
Checking whether C compiler has -isysroot - yes
Checking whether C compiler supports OSX deployment target flag

CMake Error at /Applications/CMake 2.8-2.app/Contents/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:52 (MESSAGE):
  The C compiler "/usr/bin/gcc-4.0" is not able to compile a simple test
  program.

  It fails with the following output:

  /opt/local/bin/gmake -f CMakeFiles/cmTryCompileExec.dir/build.make

通过观察论坛等在互联网上，我已经建立，这可能是与我的PATH变量的事情。这里是我的分析PATH变量：

! echo $PATH
/Library/Frameworks/Python.framework/Versions/Current/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/sw/bin:/sw/sbin:/Applications/MATLAB_R2012a.app/bin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/texbin:/usr/X11/bin:/usr/X11R6/bin

此路径变量最近发生了变化，当我配置的Python，我认为，海湾合作委员会问题，必须在相同的排序时间如雨后春笋般涌现。出了什么问题我的系统安装这个正在发生？

一些更多的细节。由指定的构建计划CMAKE_MAKE_PROGRAM是/opt/local/bin/gmake 。

我还发现，运行时，这些错误仅抛出Configure中cmake-gui 。在命令行（运行cmake ..从构建文件夹），结构精细完成：

! cmake ..

例如见-然而，在使用一些库编译时并不总是成功这个问题，我在这里问。因此，我认为有些事情可能仍然在是想错了cmake过程。
