The above libraries are provided by gtkglext, pangox-compat and libpng.  It appears that the developer used macports to build each of those, and then copied the files over.  As, I have versions of each already installed from Macports, I figured I would attempt to just run the application with just the macport versions, without installing the versions that the developer provides.

But, it didn’t work.  I believe the problem is that z88 Aurora is trying to use an older version of libpng.  Above wants 12, while I have 1.6.10 installed (libpng16.16.dylib).  Tthe error that I get when I try to run it is:
 ./aurorastartv2 
dyld: Library not loaded: /opt/local/lib/libpng12.0.dylib
  Referenced from: /Users/adershowitz/z88aurorav2/bin/mac/./z88aurora
  Reason: no suitable image found.  Did find:
	/usr/local/lib/libpng12.0.dylib: no matching architecture in universal wrapper
./aurorastartv2: line 5: 20411 Trace/BPT trap: 5       z88aurora

Since I have libpng built as universal, I find this error surprising.  Unless z88 is attempting to use the PPC version?  
So, it seems that the developer will have to fix z88 for it to be compatible with Macports.  I hope that they are responsive to your email.
