font problems in ghostview & gv

[Robert Montgomery]

I'm new to OS X and especially this whole macports / darwinports thing, 
however my first impression was, "wow, that was easy"!  However, things 
didnt work out so well in the end.  It appeared that I was able to 
install ghostview & gv (using port) with no apparent problems.   
However, I cant view any .ps files which have text in them because I 
always get an "invalid font" error.  I'm using basic built in fonts like 
Courier and Helvetica.   I've used the same exact postscript syntax to 
call those fonts for well over a decade and never had a problem from a 
variety of unix/linux flavors...  My understanding was that these were 
core fonts that were part of every postscript interpreter, which is why 
we always used these basic fonts.    So anyways, I guess I was wrong.

Anyone have an idea of how to get these (or any fonts) working?

THANKS!
Rob
