Not really, but those systems with wtmp _usually_ have a "fwtmp" with
fairly constant output format, depending on what fields you need.

I'm not familiar with "sac" can you send me a pointer?

Perl itself is very portable (congrats to the developers) but since it
subsumes many OS features those features may or may not be there
(sockets are the current bain of my life). But in this context (wtmp)
we can assume most of the *ix OS features. If you are trying to
hide your code, perl 5 offers encrypted source tools (and compression)
that may do the trick with less effort than porting to a new language.
