Could you say more about that?

Clearly the question is - where did you install redland/raptor/rasqal ?
It's not in the default library search path that is used.

It's also not in the path that `redland-config --libs` prints.

Once you figure out why that's the case, it should work.

For what it is worth, I develop on Linux and OSX and check things
work on both.  Since sourceforge abandoned helping open source devels
in this are, there are no other compile farms with a variety of systems
available.
