Hello,
I am trying to use the PS backend to make some simple line plots, using
the following script, but I get the error messages included below when I
try to plot with usetex=True. I have also included the output from
--verbose=helpful. I am using the current SVN, and I don't recall having
this problem when using 0.91.1.
Thanks,
Paul
