[R-SIG-Mac] How can I use grasp

I need to do some spatial habitat modeling in grasp (er) and I'm  
using the Mac OSX version of the R binary (1.14 build 2129)

I used the package installer to install the grasper package, but I  
get a tcltk error when I try to load it.

Do I need a tcltk version of R to run this, and If so where can I  
find this?



PS Here is the error message given when loading grasper
