in reply to IPC::Open2 failures

AFAIK IPC::Open2 does a fork/exec and only returns the result of the fork, so it's not really possible to find out if it didn't happen properly. You could do something like 
do { open2(bla, bla, bla) } if (-e $PROGRAM and -x $PROGRAM)

maybe. That would only eliminate a couple of things and leave plenty of room for $PROGRAM to croak for other reasons, tho. You could also handle the fork yourself, but that might get hairy.

    That is probably what I'll do. Loads of stuff can go wrong but -f and -x covers what is most likely to go wrong. I may throw in a ps | grep $program name to crudely cover anything else.
