In debugging a new and fascinating MakeMaker/VMS problem, I discovered this gem:
$ perl -wle "print q[12 '3' 45]"
12 '3' 45
$ perl -wle "print q[12 '' 45]"
12
'' seems to mean something special, even inside double quotes!
What's going on and what's the work around?
For the curious, the issue is this:
$(NOECHO) $(ABSPERLRUN) "-MExtUtils::Install" -e "pm_to_blib({...@argv},
'[.blib.lib.auto]', '$(PM_FILTER)', '$(PERM_DIR)')" "--" -
when PM_FILTER is not set. The argument is completely lost and perl sees:
pm_to_blib({...@argv}, '[.blib.lib.auto]', , '755')
to add to the fun, Perl will collapse multiple commas. So that's equivalent to:
pm_to_blib({...@argv}, '[.blib.lib.auto]', '755')
and the PM_FILTER argument is lost to the void. :/
