Perl under OSX, what version of Unix to use

[jtownsen]

I have several Perl scripts that I run on Win XP. I'd like to port them to 
my OS X box. From what I've read on the web, I can run Unix Perl from the 
OS X console.

--what version of Unix Perl (Linux vs Solaris, for example) should I use?
--any pitfalls I should be aware of when moving from Win to OS X/Unix?
--any related documentation you can recommend would be appreciated
Thanks
