I can't install Event::Lib for this reason:
Can't load '/root/.cpan/build/Event-Lib-1.03/blib/arch/auto/Event/Lib/Lib.so' for module Event::Lib:
the Lib.so exists in the right place:

[root@localhost ~]# ls -ld /root/.cpan/build/Event-Lib-1.03/blib/arch/
+auto/Event/Lib/Lib.so
-rwxr-xr-x  1 root root 142438 Sep 17 12:07 /root/.cpan/build/Event-Li
+b-1.03/blib/arch/auto/Event/Lib/Lib.so
[download]

I don't know why Event::Lib can't load this Lib.so.
following is a more detail install log:

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

Checking if your kit is complete...
Looks good
Note (probably harmless): No library found for -levent
