[Pythonmac-SIG] matplotlib vector graphics

[Teemu Rinne]

Thanks Christian, it does work, on one Mac out of three... 

It works on my laptop with matplotlib and stuff installed several months
ago.
It does not work on a Panther G5 with a newly installed matplotlib
(pythonmac).
It does not work on an out-of-the box Tiger with matplotlib (pythonmac)
installed.


"It works" means that the test script (below) runs ok and the ps file (144
K) behaves as expected. 
"Does not work" means that  the script runs but produces a 4.4 M (!) file
which looks ok but cannot be opened (preview, ghostscript). 

Maybe something in addition to  the pythomac matplotlib package is needed
(maybe I already have this missing package somewhere in the sediments of my
laptop) for PS to behave nicely. What? Any other ideas?
