Many people have problems compiling Pyrit on OSX Lion. The version of GCC distributed with the latest XCode no longer supports creating binary code for the PPC-architecture and Python’s setup.py does not know about that; you can get an error message like the following:
assembler (/usr/bin/../libexec/gcc/darwin/ppc/as or /usr/bin/../local/libexec/gcc/darwin/ppc/as) for architecture ppc not installed
You can solve this situation by forcing GCC to only compile code for the i386- and the x86_64-architecture. To do this, put the following into your .bash_profile:
export ARCHFLAGS=”-arch i386 –arch x86_64”
