mediawiki

[George A. Dowding]

I would like to install mediawiki using postgresql rather than mysql.  
At one time there was some useful documentation on creating a local  
port tree as well as guidance on writing a portfile.  It seems that  
the site http://darwinports.opendarwin.org/ that had the  
documentation is no longer in existence. Can somebody direct me to  
where I might find answers to the questions that I seek?

Thanks,
George
