I could use pkgutil to fish out all the files and remove them by hand (my bash foo is not foo enough to do it automagically and without ever deleting other stuff by mistake) but it is a bit of a faff.

pkgutil --unlink does not exist anymore since 10.7.  I guess it caused way too many catastrophic errors.

Thanks, I'll see what I can cook up.  Before I do something terminally stupid, does the package *overwrite* anything or are all the files listed by pkgutil --files org.r-project.gcc-42.darwin11.pkg safe to remove?
