Good thought, but he's running 6.1 and IDL 6.1 uses :0.0 if DISPLAY is not
set. 6.3 might segfault on a mac if DISPLAY is not set. The next release
of IDL fixes this problem, going back to using :0.0 if DISPLAY is not set.

But I still strongly suggest that Mac users make some effort to set
DISPLAY to the correct value by launching from an xterm or doing some
other script magic if they insist on using Terminal. Note that if the
machine is being used by more than one person with Fast User Switching, a
given X server may not always be at :0.0!!!!

Xavi should consider getting the IDL 6.3 release, which contains Mac Intel
binaries. They will run about twice as fast as the ppc bits under Rosetta
emulation.

I doubt we (ITTVIS) would look into this problem very deeply since 6.1 is
an old release. But there should be a crash log on the machine for idl
and if Xavi wants to send me the crash log (kschultz at ittvis dot com), I
could take a quick look.
