[BioC] XML and biomaRt problem?

[john seers (IFR)]

Hi All

Just a warning to other people who might be about to update and I am not
sure how to guard against this sort of problem. How are bioconductor and
CRAN coordinated? I updated my version of XML (from CRAN) and had some
problems using biomaRt. 

On issuing library(bioMart) I got a message saying that iconv.dll could
not be downloaded and reinstalling the application might fix the
problem. Also shown were messages about unable to load XML or the
biomaRt namespace.

I re-installed XML from bioconductor and it all worked again.

My sessionInfo() below is the version that is working, not the problem
configuration.

Regards
