There is a page on the Instiki wiki about getting pdf output to work ( 
http://www.instiki.org/show/InstallPdfLatex ) but it only seems to cover 
Linux (rpm-based and gentoo).  I'm wondering how to get it to work on OSX.  
I have Instiki installed on a linux machine and the 'PDF' and 'TeX' links 
are on the bottom of every page, but I don't see them on OSX so I'm 
assuming I need to install something to enable them.
