Hi Brendon,

No worries.

Yes, the McIDAS distribution contains both Tcl and Tk source, and it is
built during the McIDAS build process.

I logged back onto your machine and started nosing around.  I verified
that the Tcl and Tk shared libraries _are_ correctly being installed in
~mcidas/tcl/lib.  The problem is that this location is not correctly
being "burned" into the mcwish executable, and it should be.

After a few minutes, I found a problem in the script used to build the
Tcl/Tk distribution, tclcomp.sh.  This file had an entry that was
specific for FreeBSD 4.x; it did not allow for the possibility of
FreeBSD 5.x.  After changing the file to include support for FreeBSD
5.x; doing 'make distclean' in both ~/mcidas2005/tcl/unix and
~/mcidas2005/tk/unix; running 'rm .built* tclcomp mcwish'; and finally
running make again, I was able to build a version of mcwish that knows
where to look for the Tcl and Tk libraries.

I verified that the rebuilt of mcwish works by starting a McIDAS
MCGUI session displayed back to my machine in Boulder.

Cheers,

Tom
