Error when trying to install pylibmc on Mac OSX Lion

I've tried pip and easy_install, but I keep getting the following error: error: command '/usr/bin/llvm-gcc' failed with exit status 1

I'm running OSX Lion and the install runs inside a virtualenv, with Python 2.7.2.

Thanks in advance.

Solution

  • First a question: is libmemcached installed? If not, install it and retry. It probably is but just in case....

    If pylibmc still doesn't install the problem is probably that libmemcached is not installed in a directory where gcc can discover it (this was a macports symptom in my case), in which case you can store the location in the environment when running pip from the command line:

    LIBMEMCACHED=/opt/local pip install pylibmc
