Actually it's much simpler than this.  In the original gp_mac.py that
comes with Gnuplot.py, just make the two changes already mentioned:

in class GnuplotOpts:
default_term = 'pict'

in class _GNUPLOT:
aetools.TalkTo.__init__(self, "{GP}", start=1)

------------------------------------------------
plus, comment as follows starting around line 59:
------------------------------------------------

import gnuplot_Suites
# import Required_Suite
import aetools

class _GNUPLOT(aetools.TalkTo,
	       #Required_Suite.Required_Suite,
	       gnuplot_Suites.gnuplot_Suite,
	       #gnuplot_Suites.odds_and_ends,
	       #gnuplot_Suites.Standard_Suite,
	       #gnuplot_Suites.Miscellaneous_Events
	       ):

With these changes, Gnuplot.py's test.py module runs without error
using the new gnuplot-3.7.1a.  This works because Gnuplot.py only uses
_one_ AppleEvent call, 'exec' which is renamed to 'gnuexec' since
'exec' is a python reserverd word (there's also a 'flush' method used
but it's not an AE event, it's just a dummy).  The 'exec' AppleEvent
is defined for both the old mac-gnuplot and the new gnuplot-3.7.1a.

What's really interesting about the new gnuplot-3.7.1a on the mac,
aside from the fabulous mac-specific terminals 'pict' and 'moov', is
that there's now a 'print' AppleEvent;  it should now be possible to
support Gnuplot.py's 'hardcopy' method.  

Also, there's a few other new AppleEvents supported ('data size',
'make', 'revert', 'open') as well as a 'document' class.  I think it
should be possible to also support Gnuplot.py's 'inline' method.  Has
anyone tried this yet?
