perl5.8 problem?

[Shawn Protsman]

I was using the OS X version of Perl and haven't had any issues. Then  
I installed git-core which has a perl5.8 dependency. Now that the  
Macport perl5.8 is on my system I cannot run some of my perl programs.  
Here is an example:
@naiad ~/workspace/aestTest] ./aestTest --CbcDec
Can't locate Mac/Files.pm in @INC (@INC contains: /opt/local/lib/
perl5/5.8.8/darwin-2level /opt/local/lib/perl5/5.8.8 /opt/local/lib/
perl5/site_perl/5.8.8/darwin-2level /opt/local/lib/perl5/site_perl/
5.8.8 /opt/local/lib/perl5/site_perl /opt/local/lib/perl5/vendor_perl/
5.8.8/darwin-2level /opt/local/lib/perl5/vendor_perl/5.8.8 /opt/local/
lib/perl5/vendor_perl .) at /opt/local/lib/perl5/site_perl/5.8.8/File/
HomeDir/Darwin.pm line 34.

Next, I try to start cpan to install Mac::Files:

@naiad ~/workspace/aestTest] cpan
CPAN: File::HomeDir loaded ok (v0.80)
Can't locate Mac/Files.pm in @INC (@INC contains: /opt/local/lib/
perl5/5.8.8/darwin-2level /opt/local/lib/perl5/5.8.8 /opt/local/lib/

5.8.8 /opt/local/lib/perl5/site_perl /opt/local/lib/perl5/vendor_perl/
5.8.8/darwin-2level /opt/local/lib/perl5/vendor_perl/5.8.8 /opt/local/
lib/perl5/vendor_perl /Users/sprotsman/workspace/aestTest) at /opt/
local/lib/perl5/site_perl/5.8.8/File/HomeDir/Darwin.pm line 58.

Uhg! I'm running Mac OS 10.5.4 and Macports 1.6.0. Any help is much  
appreciated.
