[BioC] getBioC and R configuration problem

That error appears in two different locations.  The first is if you do not
have the 'http/ftp' capability set.  Try
'capabilities(what="http/ftp")'.  If this is FALSE - your best bet is to
ask this question on R-help.

The second location is immediately after that check.  The getBioC function
will attempt to read from "http://www.bioconductor.org/main.html" to
insure that it can access URLs properly.  If the first test succeeds and
this fails, it is most likely due to firewalling issues.

I've uploaded a new version of getBioC.R to the server (1.2.32) which now
has different error messages for these two situations.  The error that you
received will now only apply to the case where one does not have the
proper capabilities in their R, and in the case where R can not access
Bioconductor it will tell you that specifically.  You might want to try
the new version of gBC() to narrow down your problem.
