So now I'm running xmms and Mozilla, and they're both happy, like me.

But you said to TEST, TEST, TEST, right?  ;-)

However, trying to build TCL 8.4.1 fails, thus:

% cd build

I'm building this in order to build AOLserver, so I just removed the
use of pthread_attr_setscope() from TCL (shouldn't be a big deal), and
continued.  Then, however, the AOLserver build failed, and that one is
a bit worse:

gcc -pipe -L../nsthread -L../nsd  -o nsthreadtest nsthreadtest.o libnsthread.so -L/usr/local/aolserver/lib -ltcl84   -lpthread -lm  -Wl,-rpath,/usr/local/aolserver/lib
libnsthread.so: undefined reference to `sigwait'
