How to install Perl modules

[Mine]

Hi Ryan,

Thanks for the help.

I have encountered an error when I tried to install  p5-libwww-perl.

Error: Target org.macports.activate returned: Image error: /opt/local/ 
lib/perl5/vendor_perl/5.8.8/IO/Compress/Adapter/Deflate.pm is being  
used by the active p5-io-compress-zlib port.  Please deactivate this  
port first, or use 'port -f activate p5-io-compress' to force the  
activation.
Error: The following dependencies failed to build: p5-io-compress p5-uri
Error: Status 1 encountered during processing.

I tried port -f activate p5-io-compress and tried again but that also  
gave an error
Error: The following dependencies failed to build: p5-io-compress

Do I need to uninstall p5-io-compress

Thanks,

Terrence
