Have a look at the man page for download.file: help("download.file")
This looks like a proxy issue to me and if after reading the
download.file man page and following its suggestions you don't get
things working, you might post to R-help -- sorry, but what you are
describing is a general R problem and not Bioconductor specific. You
might also try searching the R-help list for solutions.

These environment variables must be set before the download code
is first used: they cannot be altered later by calling
