It seems to affect OpenBSD 5.6 as well.

Something along the lines of the third symlink might fix it, though that
exact link didn't seem to.  More investigation is needed.

The basic problem is that python2.7-config --ldflags includes
"-lpython2.7" but no "-L" to say where to find it.  On most platforms, a
suitable "-L" is included.
