Sounds like this could be useful to add to
instant.header_and_libs_from_pkgconfig?

I'm currently using the following code to extract the path to UFC in FFC:

  # Get include directory for ufc.h (might be better way to do this?)
  (path, dummy, dummy, dummy) = instant.header_and_libs_from_pkgconfig("ufc-1")
  if len(path) == 0:
    path =    [("/").join(sysconfig.get_python_inc().split("/")[:-2]) + "/include"]
    ufc_include = '%%include "%s/ufc.h"' % path[0]

Sounds good.
