Correction on how to update -- updating only PGProblem.pm to the HEAD version will cause difficulties (There have been more modifications to PGProblem.pm than the quick fix I made so updating just this one file won't work).
I have back ported the quick fix to remove the warning messages to the rel-2-4-patches version so
cvs update -r rel-2-4-patches PGProblemEditor.pm
should get a new copy of that file.
