Actually, re-reading this error message, it looks like libagl.so wants
to be linked with something that provides glXQueryExtension. Try to
compile with "-k-lGL".

If you don't fear to modify the FPC's sources, you can also try to
change rtl/unix/dynlibs.inc to pass RTLD_GLOBAL to dlopen call, then
recompile rtl and packages. Then the symbols from libGL (this includes
glX symbols) should be available to libagl.so too.

Hope this helps,
