rpm -qf /usr/lib/.*hmac

Which is in the nature of chkrootkit. Don't rely on it. Many of its tests
are not 100%, but just warn about suspicious file locations or activities
(e.g. a process listening on a port known to be used by some backdoor
trojans), which match a given pattern as defined in chkrootkit. It's the
admin's job to verify the report and to examine a system closer. One could
try to white-list "false positives", albeit by doing that one might run
into the pitfall of getting it wrong.
