That's exactly right. The question is why do we get that missing library? I did install eventlib.
From the cpan install:

  CPAN.pm: Going to build V/VP/VPARSEVAL/Event-Lib-1.03.tar.gz

Checking existance of libevent...yes
Checking capabilities...
  event_set_log_callback...yes
  event_priority_init...yes
Additional defines:  -DHAVE_LOG_CALLBACKS -DHAVE_PRIORITIES

I just don't quite know what I've done wrong here. I had some trouble installing eventlib, but after getting a new version that appeared to work. I thought I was home free. Thanks for the interest.
