Perl Proc::Processtable module and FreeBSD

[stan]

I planed on writing a perl script on my FreeBSD laptop over the holidays,
that would ultimetly be deployed on Solaris.

I was planing on using the Proc::ProcessTable perl module in this script to
collect memory usage data.

Looks like this module does nt support memory statistics under FreeBSD,
even though ps ddoes. 

Is there a better module to se, or should I just resort to useing a direct
call to ps (which will of course be different on the 2 OS'es?
