[PD] PDP install problems OSX

[robcanning]

Hi,

when i add -lib pdp to my .pdrc file

dyld: /usr/local/bin/pd Undefined symbols:
/usr/local/lib/pd/extra/pdp.pd_darwin undefined reference to 
_gluOrtho2D expected to be defined in /usr/X11R6/lib/libGL.1.dylib
pd_gui: pd process exited
/Applications/Pd.command: line 3: 11131 Trace/BPT trap          
/usr/local/bin/pd -rt
logout
[Process completed]

I checked /usr/X11R6/lib/libGL.1.dylib and libGL.1.dylib is there 
(well, an alias to libGL.1.2.dylib which is also there)

i'm pretty sure i have installed all the libraries needed (with fink) 
and  XDarwin.
