More Perl fun: man and System directories

Hello again!

Perl's MakeMaker seems to be a rather arcane thing. I'm trying to figure out two things:

1) Perl is creating man files in the wrong place.  My system expects  
them to be in /usr/local/share/man, but Perl is installing them in / 
usr/local/man.  Currently I'm just moving them by hand every time I  
pull-make-install, which is less than optimal.

2) In a bit of what I'm sure is OS X strangeness, Perl is creating a / 
usr/local/System directory that contains one file: "System/Library/ 
Perl/5.8.6/darwin-thread-multi-2level/perllocal.pod".  This doesn't  
seem to be useful, and I'm deleting it without anything exploding  
(noticeably) since I doubt anything is looking for a System directory  
there.  Is there a way to keep Perl from creating it in the first place?

Thanks for your time!
