You might find help more tuned to your environment by also participating on the R-sig-mac mailing list. As always start by reading the archives and posting guide, as well as using a search engine.

Note that bioconductor has its own website and support forums.

This list is still a good place for general questions about R (yes, read the Posting Guide).
