Oh, man, I feel dumb...

"Yes, it works as expected in non-oop-modules ( and I've been using Sys::Syslog in scripts for quite some time ), even on the same machine - which is a linux platform ( gentoo )."

Lies.... all lies

I went ahead and verified this ( which I obviously should have done first ), and no... it, in fact, did not work on the same machine in non-module'd code.

So sorry for that, you're suspicion was exactly correct.

By simply commenting out the 'setlogsock( 'unix' );', it all works as expected...
