Re. Windows, the issue is that we're using the mingw32 toolkit. If there is ever a mingw64, I'm sure we'd attempt a port almost immediately.

Actually, I've rolled up an x86_64 RPM for SuSE 9.1 which should be en route to CRAN. Detlef Steuer is awaiting delivery of a 64bit machine and plan to maintain the SuSE version in the longer run. It's sitting in for now.

In general, it seems to be quite trivial to take a SPEC or SRPM for the 32 bit version of a distribution and rebuild an RPM for 64 bits.

However, you might prefer to install from the source tarball anyway if you want to take advantage of high-performance libraries (some of which can not be redistributed).
