Well, the biggest problem cropped up on April 2, 2000.  If your problems
predate this, then something else may be going on.

This looks like a link problem.  The .main entry point is a system one.

OK.

>#2 has problems, and that's where I am now.  First of all, in typing

My fault!  This is what happens when copying a previous addendum and using
it as the template for a new one.  I just went through my addendum web
pages and changed mcunpack.tar.Z to mcupdate.tar.Z.  Thanks for pointing
this out.

Again, this looks like a link problem on your system.  The entry points
listed as missing above are system one.  Is it possible that you had
modified the McIDAS makefile previously to add an additional library
that must be searched on your system?  The Addenda contained a new copy
of makefile, so any change that you would have made to your makefile
would have been wiped out.

I seem to remember you telling me that you had to build a separate package
and then link against it to get the McIDAS stuff to link.  This was
most likely done in makefile, and makefile just got overwritten.  I'll
bet that as soon as you put the mods back in makefile, things will link.

>Well, over to you, any suggestions on what may be screwed up on this end?

See above.
