[ncl-talk] ncl error message with v6.4 on yellowstone

[Glen Romine]

I have a script that is failing on the call to gsn_panel (call on line 
169) with ncl v6.4.0. The error message is shown below, followed by the 
options for gsn_panel. If I switch back to version 6.3.0 I do not get an 
error. If you need info on what is being plotted in the panels, let me 
know, but I'm guessing this is not important for the debugging here.

fatal:Variable (mono_fill_scl) is undefined
