R help - Oct 2007 - R 2.6.0 Windows/lme4 Rblas load problem

Dear Windows Maintainers,

after installing R 2.6.0 on Windows 2000 and doing a complete update of the
libraries as recommended by B.Ripley, it get the error message:

The dynamic link library Rblas could not be found in the specified path....

Note that the message says "Rblas", not Rblas.dll as expected under
Windows. The
path is correct, and Rblas.dll is present

I made a copy of Rblas.dll in \bin naming it Rblas, and got it to work. 

I post this here since I don't know if this a problem of lme4 or rather the
Windows-R-build.

As Brian Ripley pointed out in a private message, it is a problem with 
the CRAN binary of Matrix that results in problems on Windows 2000 and 
earlier. The binary had the imports not optimal for some reasons - I 
guess because I used a self compiled ATLAS optimized Rblas while 
building the CRAN version of Matrix.
Anyway, a new version is on its way to CRAN and will be available from 
CRAN master within 12 hours.
(If you need it earlier, I can make a local copy available.)

Best,
Uwe Ligges
