I am migrating my dev environment to 10.8, however I am having issues with pip.
Specifically, I'm using a virtualenvs/virtualwrapper but cannot pip install psycopg2, and during the building of the psycopg2._psycopg extension, I get:
unable to execute /usr/bin/clang: No such file or directory
error: command '/usr/bin/clang' failed with exit status 1
Can anyone offer a solution to this?
