Bind9.2 dnssec-keygen problem in Redhat Linux

I have set up bind9 on several FreeBSD systems and now, I need
to make it work on a recent-vintage Redhat platform. It appears to
behave exactly as expected except for one show-stopper of a problem.
I generated tsig keys with the following command:
/usr/sbin/dnssec-keygen -a hmac-md5 -b 128 -n HOST hostname.domain-keyname
It generates two perfectly good-looking keys that never work
with the complaint being an invalid signature.
Mar 13 00:21:07.829 client 192.168.253.207#34321: request has invalid signature: tsig verify failure
I've spent the entire day off and on beating my head on this
one, trying several sets of keys, etc. What could it be?
The dnssec-keygen command is actually lifted from one I used for years
on FreeBSD to generate keys that worked. I tried 128 and 512-bit
keys. By the way, rndc commands do work fine and I tried zone
transfers both from the localhost and a remote host with exactly the
same negative results which kind of rules out clock problems.
Thanks for any helpful ideas.
