I used to see it (I stopped building libmng over a year ago because I couldn't
find any need for it). In my case I used to
sed -e 's%-O3%-O3 -fPIC%' \
which is nearly the same as you are doing..
I also have to force it in a52dec-0.7.4 (add to CFLAGS when running
configure) and ghostscript-8.70 where I took the fix from cblfs and
adapted it when the file moved -
sed -i "s/CFLAGS='/&-fPIC /g" base/unix-dll.mak
When I first played with pure64 there were several other packages
that needed fPIC added. Slowly, the old ones are either being relaced
or dropping out of use.
After tragedy, and farce, "OMG poneys!"
