[R-SIG-Mac] affy pcg installation and XML installation in Panther

[Tiago R Magalhaes]

hi to you all

I am trying to install the affy package from bioconductor and I have 
been very unsuccessful!

I have a G4, MacOSX panther and the R version 1.9.1 installed.

One of the problems is that the XML tools are not installed. I tried 
to install a package called libXML2.pkg, but there's an indication 
that it might be for Jaguar only.
When I installed BioConductor from the CRAN repository it gave 23 
warnings most of them concerning XML.
[1] "Installing XML" Note: Package XML not found in any known repository.

Any idea on how to solve the problem (if it's solvable...)

I am sorry about this basic question, and for those of you in the 
bioconductor list this might be the second time with the question
