Russ,

Actually, it's a bit scarier than that.  When I first had the problem, I 
used ldd to see which shared libraries were needed or expected by my 
module.  And only libk5crypto showed as 'not found'.  There was an entry 
for libkrb5.  However, what I didn't notice was that the latter was the 
version in /usr/lib, which comes installed with FreeBSD and is not the MIT 
version.  That's why I say 'scary', because if not for the missing 
libk5crypto, I might never have noticed that I wasn't using the correct 
libkrb5 either.  Whether or not this would have caused more subtle 
problems later I can't really say.

Anyway, thanks for the pointer to info about -R.  I now see that -R 
appears in the Makefiles used in the MIT K5 build as well.

Mike
