Exactly, thats why pkg-config might not be the right tool. I would
suggest that the features of pkg-config get extended by boost needs.
( extend => reimplement as boost application )
Thus one has to add the ability to specify flags that affect the output.

In my opinion that feature must be provided by boost. Imagine suse
packaging boost with boost_python-1.32.pc and boost_threads-1.32.pc ...
and redhat doing the same but the pkg-config files get named like
libboostpython-1.32.pc ... The users of boost would suddenly have the
same problem, just on a different level.

Yes, that makes using boost much simpler. One could also output proper
flags for include directories, so packagers could install several
versions of boost on one system.
