error: command 'gcc-4.2' failed with exit status 1
The reason for this error is that Apple has removed from Xcode the assembler for PPC, while the core system retains their PPC images in the fat binaries. If you run file /usr/bin/python you will likely find the following:
/usr/bin/python: Mach-O universal binary with 3 architectures
/usr/bin/python (for architecture x86_64): Mach-O 64-bit executable x86_64
/usr/bin/python (for architecture i386): Mach-O executable i386
/usr/bin/python (for architecture ppc7400): Mach-O executable ppc
Python compiles C extensions with the same compiler flags that Python itself was compiled with.
The solution? Install glue using this line:
$ sudo env ARCHFLAGS='-arch i386 -arch x86_64' pip install glue
