I have installed demeter using Macports on 10.12.1 and while hephaestus seems to run normally, athena has some trouble with graphics.  The usual athena perl based panel shows up just fine, but upon loading some data, there is always an error when gnuplot is invoked to plot graphics (as reproduced below).  It would seem that the command “set” is missing the first letter.  Does anyone have a suggestion as to what to check to fix this?
