Duh, sorry, I do not know why I did not see that.  I was just looking  
at order of definition of the PATH, not the actual order inside each  
path.  I have a new echo'd out path of
/usr/bin:/bin:/usr/sbin:/sbin:/Users/me:/usr/local/bin:/usr/X11/bin:/ 
Users/me/bin:/opt/local/bin:/opt/local/sbin

perl -V is now showing what I want
     /System/Library/Perl/5.8.8/darwin-thread-multi-2level
     /System/Library/Perl/5.8.8
     /Library/Perl/5.8.8/darwin-thread-multi-2level
     /Library/Perl/5.8.8
     /Library/Perl
     /Network/Library/Perl/5.8.8/darwin-thread-multi-2level
     /Network/Library/Perl/5.8.8
     /Network/Library/Perl
     /System/Library/Perl/Extras/5.8.8/darwin-thread-multi-2level
     /System/Library/Perl/Extras/5.8.8
     /Library/Perl/5.8.6
     /Library/Perl/5.8.1

Thanks for all the help on this one.
