Your copy of gnuplot does not support pdf output. This is quite
common in linux-land, as most distros (eg Debian, Ubuntu) ship a
precompiled version of gnuplot with pdf output disabled.
I'm not sure what the best thing to do is. We have the following
options:
a) leave things as they are now, (ie let gnuplot fail) but issue
a more informative statement
b) remove the pdf option altogether, since we cannot be sure
that it works
c) do a run-time check (I don't like this)
d) do a one-time check and store its results into the user's
preferences somehow
Ah, I had forgotten that gnuplot might not support PDF output.
But in fact we already have a check for that (a one-time runtime
check, which is not elegant but, I think, better than disabling
PDF). So I've now connected that check to the new functionality:
one should get an informative error message on trying to generate
PDF when gnuplot can't do it.
Allin.
