You *very probably* didn't compile all of suitesparse with -fPIC,
then. I recall it was tricky; it needed changes in more than one
place. Try afresh, and pay attention to the compile commands shown (or
tee them into a file) to check out where -fPIC is missing. If you link
with METIS, it needs -fPIC too.
