Perl 5.10?

[Shawn Protsman]

I installed Perl 5.10 today. Unfortunately it seems like there is  
confusion between 5.8.8 and 5.10. I tried to run cpanp and this was  
the output:

@naiad ~] cpanp-5.10
Can't locate CPANPLUS.pm in @INC (@INC contains: /opt/local/lib/ 
perl5/5.8.8/darwin-2level /opt/local/lib/perl5/5.8.8 /opt/local/lib/

lib/perl5/vendor_perl .) at /opt/local/bin/cpanp-5.10 line 11.
BEGIN failed--compilation aborted at /opt/local/bin/cpanp-5.10 line 11.

How do I get macports Perl to focus on 5.10 and not get confused with  
5.8.8?
