Darren, This is fixed at github. You can git pull and reinstall. Since I am working on integrating Matt's larch with Demeter, I have instrumented one of the main choke points in Demeter with a useful (to me) screen message that helps me track the flow through the parts of the program relevant to switching between Larch and Ifeffit. Unsurprisingly, I hadn't tested it quite all the situations, one of which was borken and is found in Hephaestus' f'/f" tool. Thanks for the heads-up.

When I run hephaestus, select F'/F'', and then select any element in the table, the program bails and I get some feedback in the terminal: Can't use string ("Demeter") as a HASH ref while "strict refs" in use at accessor Demeter::devflag (defined at /home/darren/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter.pm line 100) line 8. Sometimes, "<F> line 29." is appended to that error message. I'm running the forthcoming kubuntu 13.04. Any ideas how I can improve my install?
