I am a complete amateur at this.  I'm trying to install and run SciPy, specifically ndimage, on my work computer (I'm doing image analysis--I'm used to using IDL but don't want to pay for it).  It is a 64 bit macbook pro running OS X Lion, I am using python 2.7.  Reading error messages and looking around on the internet leads me to think that I need to install PIL in order for everything to work.  I am trying to install it going by the instructions, but I keep running into problems.  Specifically it spits out:

running install
running build
running build_py
running build_ext
--- using frameworks at /System/Library/Frameworks
building '_imaging' extension
gcc-4.2 -fno-strict-aliasing -fno-common -dynamic -isysroot /Developer/SDKs/MacOSX10.6.sdk -arch i386 -arch x86_64 -g -O2 -DNDEBUG -g -O3 -DHAVE_LIBZ -I/System/Library/Frameworks/Tcl.framework/Headers -I/System/Library/Frameworks/Tk.framework/Headers -IlibImaging -I/Library/Frameworks/Python.framework/Versions/2.7/include -I/usr/include -I/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c _imaging.c -o build/temp.macosx-10.6-intel-2.7/_imaging.o
unable to execute gcc-4.2: No such file or directory
error: command 'gcc-4.2' failed with exit status 1

and then dies.  Am I making this more complicated than it needs to be?  I have installed xcode and that does not seem to fix it.  

Thanks for any help, keeping in mind that i'm a total newb.
