Hi, netters,

recently i've been trying to install biomaRt. I'm using Suse and have R 
2.3.0 installed.

> source("http://www.bioconductor.org/biocLite.R")
> biocLite("biomaRt")

Then I was told XML and RCurl are dependencies. And the program proceeded 
to download XML,RCurl and biomaRt, followed by installing them one by one.  
but when XML was being installed, an error message came up:

checking for xml2-config... no
Cannot find xml2-config
ERROR: configuration failed for package 'XML'

The same for RCurl. And then, not surprisingly, installation of biomaRt 
failed too.

I don't know what happened. It seems that XML and RCurl has been 
downloaded, and all the other checkings were ok, except for the 
configuration files.   Could anyone tell me how to solve the problem?

Thank you very much!
