Bug report
Bug summary
I want to install a specific version of matplotlib (1.3.1) in a virtualenv. I created the virtualenv, activated it and ran pip install. Which resulted in the error: Command "python setup.py egg_info" failed with error code 1. It appears that freetype and libagg cannot be found by pkg-config. I checked if the libfreetype6 was installed with ldconfig -p | grep freetype. Showing that freetype is properly installed. However when I check the pkg-config it appears that freetype is not listed in it, as pkg-config --list-all | grep freetype returns no results.
As a sidenot, since the upgrade to Ubuntu 18.04 I had problems with libfreetype rendering fonts, and downgraded and marked the package with apt-mark hold, as suggested here, which fixed the font rendering issues. To test if this is the reason for the bug I undid it and upgrade to the most recent version of libfreetype (still resulting in the same error)
Code for reproduction
