Comment(by matt.cottrell@…):

 Replying to [comment:24 ryandesign@…]:

 >  Hope this looks ok. I did not know how to reproduce the runtime libpng
 error you encountered, so I could not verify that these changes fix it.

 Unable to test fix to runtime libpng error.  ARB build fails with missing
 library (ld: library not found for -lXaw).  Attached Portfile.3.diff fixes
 this and adds some longstanding missing depends needed for printing from
 ARB (xfig and gv)

 After we fix this please stay tuned for more Portfile patches to come.
 Taking them one at a time.
