Pyraf building wrong version of gcc on os x

Question

I have installed python 2.7 through enthought 7.2 package, i've been trying to install pyraf package, however everytime i try to install it i got the following:

copying lib/pyraf/wutil.py -> build/lib.macosx-10.5-x86_64-2.7/pyraf
running build_ext
building 'pyraf.sscanfmodule' extension
creating build/temp.macosx-10.5-x86_64-2.7
creating build/temp.macosx-10.5-x86_64-2.7/src
gcc -fno-strict-aliasing -fno-common -dynamic -arch x86_64 -isysroot

-I/usr/X11R6/include
-I/Library/Frameworks/EPD64.framework/Versions/7.1/include/python2.7 -c
src/sscanfmodule.c -o build/temp.macosx-10.5-x86_64-2.7/src/sscanfmodule.o
gcc: error: x86_64: No such file or directory
gcc: error: x86_64: No such file or directory
gcc: error: unrecognized option ‘-arch’
gcc: error: unrecognized option ‘-arch’
error: command 'gcc' failed with exit status 1

So i thought it was an architecture issue, so i reinstalled packages (i386, XCode) and then got this

running install
running build
running build_py
copying lib/pyraf/svn_version.py -> build/lib.macosx-10.5-i386-2.7/pyraf
running build_ext

src/sscanfmodule.c -o build/temp.macosx-10.5-i386-2.7/src/sscanfmodule.o
gcc: error: i386: No such file or directory
gcc: error: i386: No such file or directory
gcc: error: unrecognized option ‘-arch’
gcc: error: unrecognized option ‘-arch’

Afterwards it seemed to me that the real problem was a gcc version problem, so i looked for any gcc installed, i found this:

so i decided with an alias line in my .bash_profile file pointing out to the correct gcc version, it didn't work at all.

I tried setting up gcc environment and building the pyraf setup.py and got this:

Giotto:pyraf-dev Huguito$ export CC=/usr/bin/gcc-4.2

Giotto:pyraf-dev Huguito$ python setup.py build

gcc: error: i386: No such file or directory

error: command 'gcc' failed with exit status 1

If i type the gcc command but without the -arch i386 flags:

Giotto:pyraf-dev Huguito$ gcc -fno-strict-aliasing -fno-common -dynamic -isysroot 
/Developer/SDKs/MacOSX10.5.sdk -DNDEBUG -g -O3 -isysroot /Developer/SDKs/MacOSX10.5.sdk

src/sscanfmodule.c -o build/temp.macosx-10.5-i386-2.7/src/sscanfmodule.o

it seems to compile fine, however after recompiling it ignores it and dosen't work at all.

try it. install Command Line Tools from your Xcode. in Xcode -> Preferences -> Downloads -> Components ->Command Line Tools
