help - macports modules not found?

[Johnson, Matthew]

Ah, thank you so much Josh!  I was not understanding the distinction between things like cairo, gtk, et al and the bindings/whatever that allow perl to use those.

Now that I understand that, I've managed to install all the modules that I need.  So now I get the much shorter error: segmentation fault.  i think i'll give up now.  bleh.  (if anyone's looking for a project, i'm just trying to get this program to run on mac: http://sourceforge.net/projects/haplopainter/)
