cyradm - urgent!

Hello all,

i've been installing cyradm, the perl module perl::imap (or so...) and
still: cyradm does not work! i tried also to recompile but no help. The
effect is, if i call cyradm, i just get on the next promptline, nothing at
all happesn...

My system: Red Hat 8.0
Cyrus: 2.1.11
Sasl : 2.0.17

any idea?? Thx in advance for any input...
regards,
Roger
