[BioC] XML package downloading problem with bioconductor.org

[Liu,Bin]

Hi, I am trying to download the XML package that is required for "GenomicFeatures" package. However, I got following error message. 
It seems that the gz file couldn't be downloaded. Whenever the downloading reached 751kb, an error was displayed.I am using R2.14.0 devel version.
It works for other packages. Thanks
