Comment (by ryandesign):

 For most dependencies, MacPorts requires them to be installed by a
 MacPorts port. TeXLive is one of the few exceptions; a non-MacPorts
 TeXLive installation can be used by MacPorts ports. If you want that to
 happen, edit macports.conf and put `/usr/texbin:` at the beginning of
 `binpath`.
