version conflict for package "Tcl": have 8.4, need 8.5
    while executing
"package require Tcl 8.5"

OSX 10.8 has both 8.4 & 8.5 built in and it seems the default tclsh points to the 8.5 install, but it seems the method Pd uses to find Tcl & Wish.app end up choosing 8.4 instead.

Anyway, I'm asking mainly because with 8.5 you can get "retina" screen enabled fonts which are nice and crisp as opposed to Pd's current blurry fonts. I remember trying this about 6 months ago after I got the machine but ran into the same problem and moved on. Would be nice to provide a patch and some info on how to make it work.
