I am having some trouble with compiling mapscript (is a package from pypi containing C code) with the default clang compiler using pip.
Here's my attempt:-
$ sudo pip install mapscript

How do I try installing mapscript with another compiler? Is there a way to explicitly specify a specific compiler that pip will call upon when compiling the C code in a pypi package?
Setting the CC environment variable seems to work, e.g.:
env CC=/usr/bin/gcc-4.0 pip install pyOpenSSL
