Russ,
Thanks, that fixed it! I must say, I didn't even know about the -R option
to gcc and can't find it in the gcc man page. What does -R do anyway?
I had just assumed that the '-L/usr/local/kerberos/lib' would be
sufficient to tell the linker where to find the libraries. Why did only
libk5crypto have a problem and not, for example, libkrb5?
(My knowledge about linking is clearly inadequate).
Thanks again.
Mike
