Karl,
I've been running 7.5/4.1 on Linux for a while now.  So, at
least it works somewhere, which implies that if there is
a problem, it is either with the installations, the platform,
or the link command.

Can you check to see if your libtk.a and libtcl.a (or libtk.so.1
and libtcl.so.1) are actually libtk4.1.a and libtcl7.5.a instead
of old 4.0 and 7.4 versions?  I suspect that they are present and
the link command (which lists -ltk -ltcl) is finding 7.4/4.0 libraries
even though it was compiled with 7.5/4.1 includes.  If this is the
case, simply replace -ltk -ltcl with -ltk4.1 -ltcl7.5 in the 
Makefile.conf file.

We recently got 7.5/4.1 at work on our Solaris boxes and as soon
as I get BLT installed on top of those, then I'll be able to 
test it.
