in thread combination of multiple installed Perls and some environment variables cause segfaults

Re: Question 1: I understand that the different perl versions are incompatible. But then why does doing  PERL5LIB='/Users/derek/local/lib/perl5' pnmquant 256 img.pnm segfault (well, I know why, because that PERL5LIB is for 5.14 and pnmquant uses /usr/bin/perl v5.10) but PERL_DL_NONLAZY=1 PERL5LIB='/Users/derek/local/lib/perl5' pnmquant 256 img.pnm produces the correct result without segfaulting? Seems like PERL_DL_NONLAZY is doing something, but I don't understand what, apparently.

The Netpbm scripts (clarification, just in case: Netpbm is not a Perl module) have /usr/bin/perl hard-coded in their #!, so I don't think changing their install location will affect things.

[marioroy]: LA my @music_times = qx(find \$HOME/Music/ Albums -type f -iname \'*.mp3\' -exec mp3info -p \"%S\\n\" {} \\;);
[marioroy]: Only 2 backslash \\n
[marioroy]: LA no space before Albums
[Lady_Aleena]: Good guh! I think I will use File::Find when working in perl. That is too many toothpicks.
[marioroy]: mp3info must be in the PATH
[marioroy]: LA ++
[Lady_Aleena]: marioroy, this is forcing me to learn perl modules to use instead.
[marioroy]: qx isn't fun if having to backslash ' and " and \.
