Well, at least I get something different.

Here's the GraphicsMagick situation.  First, the output of the "port installed 
GraphicsMagick" command:
  The following ports are currently installed:
    GraphicsMagick @1.3.18_0+q32 (active)
    GraphicsMagick @1.3.19_0+q8
The 1.3.18 version was created by following the InstallingOlderPort 
instructions, but adding the following in the Portfiles:
  configure.compiler macports-gcc-4.8
I don't like touching Portfiles, since I'm so new to them, but I could not find 
any other way to compile with the correct compiler.  I did add the -d option to 
the install command so I could verify the correct compiler:
  sudo port -d install +q32
from within the GraphicsMagick folder that I created by following the 
InstallingOlderPort guide.

Then I did 'make clean', 'make -j4'.  (Actually I did it with and without -j4, 
same results.)

Here is the new build error I get:

Line 31 of file-editor-tab.cc is a #include that brings in something from what 
appears to be Qscintilla, which for me is at Version 2.7.2.

At this point I decided I'd had enough for one day.
