How to install Perl modules

[Mine]

Hi Ryan,

Initially when I tried your instructions I got an error relating to  
p5-io-compress
when I tried to install p5-libwww-perl. It eventually installed but  
when I looked
into /opt/local/lib/perl5/ I found that two new directories were  
created "site_perl"
and "vendor_perl". vendor_perl contained a 5.8.8 directory with what  
looked like
a duplicate of the files installed in "site_perl".

 From what I can see, some of the files I was trying to install —  
HTML, HTTP, LWP,
URI etc were not installed in the original 5.8.8 Perl directory but  
in the new directories.
Does this mean that the files are not properly installed?
