[BioC] load AnnBuilder and install XML

[zhihua li]

Hi netters

I've downloaded and installed AnnBuilder. When I loaded it, I was told that 
the dependent package XML had not been installed.
According to the manual of AnnBuilder, the XML package can be found in 
CRAN. But I can't find a windows binary there. Instead, I went to 
http://www.omegahat.org/RSXML/index.html and downloaded XML_0.97-0.zip 
there. 
I used the menu of "install packages from local zip file" and it seemed 
that I've installed XML sucessfully:
package 'XML' successfully unpacked and MD5 sums checked
updating HTML package descriptions

But then when I loaded AnnBuilder, I still got:
> library(AnnBuilder)
Loading required package: Biobase 
Loading required package: tools

Loading required package: XML 
Error in library(pkg, character.only = TRUE, logical = TRUE, lib.loc = 
lib.loc) : 
        'XML' is not a valid package -- installed < 2.0.0?

I'm using R 2.0.1 actually.

Is there something wrong with windows version of XML?

Thanks a lot!
