Do you have several libpetsc installed?

It might be a combination of pkg-config and distutils. In the latter
library_dirs and libraries are two different arguments to the Extension
class. This means that we split the library dirs and libraries from each
other destroying all information about library_dir to library order.
This is actually preserved in the pkg-config file.

If we are going to shift to CMake we need not only ditch pkg-config, but
also distutils. Kent has added support for CMake compilation for VTK and
ITK based modules, which more easily is find using find_package calls.

I can have a look at this next week. I think using CMake instead of
distutils also opens up for easier compiler configurations, as this can
be quite obscure in distutils.
