[Rd] LAPACK and BLAS libraries

[Prof Brian Ripley]

Please don't post to multiple lists.

It seems you are using Windows, but have not told us so: this is one of 
many things in the posting guide you have not followed (and that is why 
you did not get at least one answer on R-help).

There are many packages on CRAN that use LAPACK and work under Windows. 
You should test your setup on one of those.  (DPackage is one of the first 
in C collation.)
