But there are no shared versions of DGA libs, that is the problem.

Sorry, no time to have a look on Allegros building system for the next
two week (learning for exams).

I know about similar plug-in systems in XMMS and libao (from
vorbis-tools). They have no non-PIC related problems, so it should be
possible. If I understand correctly, using the plugins loaded via dlopen
does not change anything on the code references inside the plugins, so
it is still the same code as if it would be linked into the shared
library (like in previous allegro versions). The problems moved from the
main library into the plugins.

Okay, limit the statement to shared libs ;) BTW, the compiler message
was:

| /usr/bin/ld: XF86DGA.o: relocation R_PARISC_DPREL21L can not be used
| when making+a shared object; recompile with -fPIC
| /usr/X11R6/lib/libXxf86dga.a: could not read symbols: Bad value
| collect2: ld returned 1 exit status
| make: *** [lib/unix/liballeg-3.9.36.so] Error 1

Same thing that you discovered too.

Thx,
Eduard.
