Can't downgrade R after R-devel install (MacOS X Snow Leopard)

R-sig-maccers:

I recently installed R-devel to properly check a CRAN package I developed,
but I didn't want to remain "unstable" for my work, so I re-installed R
3.0.1 but I can't seem to get it to launch, I keep getting the following
error:

*** If I re-install R-devel I can use that without the crash, but I don't
want to be stuck with that version for my work.  Is there a way I can do a
"clean" install of R 3.0.1?

Thanks!
