Still puzzling. I sort of understand what you are seeing, but it makes
little sense, isn't consistent with my understanding of how package
loading in perl works, and certainly is not something I have seen before.
Try putting
use Graphics::GnuplotIF;
somewhere near the top of lib/Demeter/Plot/Gnuplot.pm. Doesn't much
matter where. After line 57 would be fine.
If that works -- great! Both of my suggestions do no harm, so I'll just
commit them to github....

Hm, we're getting somewhere. Putting the 'use Carp;' line now has dathena

Use of uninitialized value in subroutine entry at

and when you exit, it pops up a dialogue box with this error:
Use of uninitialized value in stat at
/usr/local/lib/i386-linux-gnu/perl/5.24.1/Demeter/Plot/Gnuplot.pm line 270.
The program seems to behave ok otherwise, but I don't know what operations
would have problems with an uninitialized gnuplot module variable or
subroutine. Why would it have issues initializing in the first place
(or not finding the Carp module)?
Thanks for the help so far!
