 Could you apply the segmentation fault solution described by
 [http://djconnel.blogspot.de/2012/03/installing-xgraph-on-mac-osx-
 lion.html], please?

 {{{
 "But then I faced a tougher problem: I was getting a persistent
 segmentation fault when I ran it. gdb wasn't turning up the problem,
 either.

 The clue was in the compiler warnings: xgraph plays fast and loose with
 casting between addresses and integers. Sometimes that works, sometimes...
 So in desperation I checked the gcc man page and started reading, looking
 for an option which treated all integers as longs. I didn't think this
 would work, because external libraries might not cooperate.

 I didn't find it. But what I found instead was the "-m32" option to
 compile the code in 32-bit mode even on a 64-bit machine. Hmm... seemed
 promising. I added this to the head of the "CFLAGS" definition in Makefile
 (Makefile having been generated with "configure", so this isn't the best
 approach). I tried it and, ding-ding-ding-ding, the code ran. My little
 victory shout was probably out of place, since I was on Caltrain at the
 time...

 So now it works."

 Thank you for fixing the build issue yesterday...
