[PD] blanco patches in pd-0.37-test4 OSX

[tim.vets]

Hello,

I used pd-0.36 on osx before, but now it wont work anymore.
Recently i upgraded to osx version 10.2.6.
I installed TclTk8.4.2 and tried to run pd-0.37-test4.
I can see the pd window and choose "new" from the file menu.
When I try to put something in the new window nothing happens.
Also when i open an existing example patch i get a blanco window.
The previous version (0.36-something) now has more or less the same problem.
On trying to put an object there, pd just shuts down and the terminal says:
Consistency check failed: glist_findrtext
pd_gui: pd process exited
What could be the problem here ?

thanks
