Please do!

I have tried the latest git clone to adapt it for OS X and QuantumSTEP.
I get a first window popping up but then it fails with an undefined selector 
(see 3).

Some observations so far:

1. the code uses [[NSMutableString new] initWithString:@"..."]

This fails on OSX, because +new already calls -init and returns some NSCFString
subclass that does not understand -initWithString. Please use [NSMutableString 
alloc] initWithString:...

2. OS X and QantumSTEP don't have the PS() operator functions

I have added some macros to my code to build an NSBezierPath and fill/stroke it.

3. there is no [con getSymbolData] method in drawRogueCharacter

Shouldn't that be getCharacterXpmData?

4. the code uses strndup() which is a GNU/Linux extension not available 
everywhere

I have added the code from 
http://opensource.apple.com/source/gcc/gcc-5575.11/libiberty/strndup.c

5. the GhackInfo.plist is missing some or using different keys for OS X (icon 
file, executable)

BR and please continue the good work!
