Comment (by mojca@…):

 For gnuplot:

 1.) I attached a new patch for src/variable.c here (just replace the old
 file with this one). There is no ticket for that patch except for this
 (https://sourceforge.net/p/gnuplot/patches/627/). The patch has now been
 applied upstream, but the exclamation mark is needed to search for fonts
 in /Library/Fonts recursively, else fonts from, say,
 /Library/Fonts/Microsoft aren't found. Not that anyone uses that obscure
 feature for PostScript plots ... ;) I asked the author of the previous
 patch why he removed the exclamation marks, but he wasn't able to recall
 why. So: exclamation marks need to stay.

 2.) See #38798 for [http://trac.macports.org/attachment/ticket/38798
 /gnuplot-demo.patch this patch]

 3.) #34072 can be closed as fixed.

 Thank you.
