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.
