R help - Feb 2012 - How do I get the CEM (coarsened exact matching) package to run?

Hi, 

I am running a MacBook Pro with OS X 10.6.8. When I try to load library(cem) and
run any function, R crashes. Any suggestions as to why this is? Thanks in
advance. I think the problem is that I don't have all the
"infrastructure" I need to run CEM, but I have no clue what to do
either...

This probably means that tk wasn't installed properly.
