I suspect that this is due to a bug with the parallel threading code
on solaris -- the system I used to compile to code on got a specific
error about a rmutex problem (see below), but yours might be hanging
anyway w/out giving the error.  It looked like this error was a
solaris bug but then it appears now that maybe it is not.. Anyway, I
compiled a version without parallel threading enabled, and this is now
available on the grey ftp site, as the standard
pdp++_2.1_bin_SUN4.tar.gz file -- I moved the pthread ones to
SUN4pthread, etc.  Give this a try and let me know if it fixes the
problem.  If anyone has more info about how to get pthread working on
solaris, let me know..
