I have had trouble loading driver plugins using Player 1.6.2 (and earlier).
I got it working by editing the "server/Makefile.in" file and changing the
line that says "player_LDFLAGS = -Wl --export-dynamic" to "player_LDFLAGS =
-Wl,--export-dynamic". That comma makes a big difference.
I was using Redhat 9 and also a uClibc toolchain. This change made it work
on both file systems.
