[R] won't install properly on Mac 10.3.2

[Hank Stevens]

R version 1.8.1, Mac OS X 10.3.2

I have tried searching for this  problem and its fix, but to no avail.
-Everything seems to download and unpack fine. I double click on StartR, 
however, and it just winks and fails.
Any thoughts?
Thanks in advance,
Hank
