Two ports which install files to the same place conflict-- you can't  
have two different versions of a file at the same path location.   
With some work, it is possible to install multiple versions of some  
ports (like Perl, Berkeley DB, GNU autoconf, etc) using a version #  
suffix, and symlink the version you prefer to the unqualified name:

% ls -l /usr/local/bin/perl5
lrwxr-xr-x  1 root  wheel  24 Mar 23  2006 /usr/local/bin/perl5@ -> / 

...but it doesn't magically happen.
