Building Swarm on Linux

[Beemer]

So I'm trying to build Swarm on Linux (Slackware distribution) and I'm
having trouble -- not with Swarm itself, but with the BLT packages for
Tcl/Tk.  Before I go into all the ugly details (things compile, but
then can't link properly), has anyone else had problems with this, or
got any generic advice on dealing with this package?  The README files
and such distributed with it are particularly unhelpful...

Thanks,
