Why on earth is a shared lib linking against a static lib?

We had this problem before with ORBit, which was building its shared libs from
static ones.  The solution was a pretty messy edit to configure.in and a
Makefile.am to recompile all objects -fPIC for the shared libs.  Sounds like this
may be required here too.

This is why Debian policy requires shared objects to be built with -fPIC, static
without (section 4.2).  If something is not being built this way, a bug report
would be in order.
