[egenix-users] Error compiling egenix-mx-base (again)

Every time I try to pip install egenix-mx-base in a different machine
it errors out, does it pay off to override distutils/distribute
internals? This time I think is because distutils/distribute uses
clang when it doesn't find gcc-4.2 but your code do not. I'm also
pasting the error when I create a gcc-4.2 symbolic link pointing to
clang:
