Yes, there is an issue with the BioC website (investigating) and I didn't mean to imply otherwise. For now, as you discovered, use (note the 'www').

Did you see the segfault with a recent R or an older one? If more recent, then it might be worth trying to reproduce and tracking down the bug. mailing list Received on Tue Sep 05 00:58:16 2006
