Hm, we're getting somewhere. Putting the 'use Carp;' line now has dathena
come up, but delivering this error:
Use of uninitialized value in subroutine entry at
/usr/local/lib/i386-linux-gnu/perl/5.24.1/Demeter/Plot/Gnuplot.pm line 29.
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!

Well ... the beam just dumped, so let's see if I can figure this out....
Demeter does not use Carp::Clan, so the version number of
libcarp-clan-perl is irrelevant.
This is a puzzler for me. I have never seen this problem over many,
many versions of perl. So there is something I don't understand about
your system. I cannot reproduce this problem, so it's going to be
difficult to resolve.
Try this:
Put
use Carp;
just after line 257 of lib/Demeter/Plot/Gnuplot.pm. Line 257 is the one
that says
{ no warnings 'redefine';
No guarantees, but maybe that'll help.... Let me know.

Hello -
We're trying to install demeter on a 32-bit system running Debian 9.2
Stretch. The 'perl Build.PL' and 'Build' run into no issues, but when
we try running 'Build test' we get the following error messages:

The "croak" command not getting found appears to come from the "Carp"
perl module - we have version 6.06-1 of the 'libcarp-clan-perl' package
installed. Any suggestions as to what's causing this error? Again, the
'perl Build.PL' command shows no issues with the installed modules, but
since most of them were installed from the Debian repository, maybe
there's a discrepancy with the modules installed when we run './Build
installdeps'?
Thanks for any assistance -
