[CIG-SHORT] Problem running Pylith binary on 64-bit Mac OS X

[Brad Aagaard]

Isabelle-

Yes this was a execution/setup issue, PETSc tries to open an xterm when 
start_in_debugger = true and this can cause problems if X windows is not 
running (often true on OS X).

I just checked and this error was introduced in Aug when Charles changed 
the value of this flag in the twohex8/twocells example. None of the 
other examples have this flag set by default. I just fixed this change 
for the development version so it shouldn't be in the next release.
