Does this file exist on your machine?

I noticed in the error message that Unix style path separators are
being used (/) not Windows style (\). This could be the cause of the
problem - looking back over the mailing list, about 30 November 2007
Gregory Warnes made a change as part of RPy 1.0.1 to deal with a
similar problem with loading the lapack library. I had a quick look
in SVN but couldn't work out what he actually changed in the code.
