Ok, now I'm pretty sure it does search backwards. I rebuilt parl with
only the hacked PAR.pm in place (it has a 'warn "hi\n"' in it, so this
shows up whenever it is use()d.) Note the order of @INC, with PAR.pm
currently in the first directory. Note the last command, where pp sees
the lib/PAR.pm and parl sees site/lib/PAR.pm.
