Yes :-)  -fPIC doesn't work for the code generated by GHC.    You can =
make shared libraries without -fPIC, but that also imposes constraints =
on the code, constraints which the code generated by GHC doesn't satisfy =
at the moment.  I can't remember the exact details, but John Levine's =
Linker book is a good place to start.
