I'd rather just grab current prebuild binaries from any CRAN mirror, eg

	http://cran.r-project.org/bin/linux/ubuntu/

as Vincent and Michael do a really excellent job rebuilding my Debian
packages for Ubuntu x86 and amd64, typically within a day. There are a
few other goodies there too, see the README in the aforementioned
directory.
