Porting to FreeBSD

[Daniela]

Hi there!

I found many interesting Linux programs on sourceforge.net and other sites, 
but they're not in the ports collection. So I thought I'll port some of these 
to FreeBSD. However, I'm still pretty new to FreeBSD and I never ported 
anything.

I can't even compile most of the programs on my system, and I'm almost sure it 
has to do with dependencies in 99% of all cases.
How do I find out what ports/programs it depends on? And yes, I have RTFM, but 
I still have no clue.
