R devel - Dec 2006 - Problem with tuned Rblas from CRAN with R-2.4.0

I encountered the following problem in R-2.4.0 for Windows binary downloaded
from CRAN (data from R-help post by Ethan Johnsons).  I was also using the
contributed binary Rblas.dll for Intel P4 chip.  The problem doesn't occur
with the default Rblas.dll.

0.0004529, 0.0000301)
fit.lm<-lm(y~x)
summary(fit.lm)

I got the following popup window error message

   The procedure entry point zdrot_ could not be found in the dynamic link
library Rblas.dll


After closing the popup, the following was printed in the console:

Error in chol2inv(Qr$qr[p1, p1, drop = FALSE]) : 
        lapack routines cannot be loaded
In addition: Warning message:
unable to load shared library 'C:\R\R-2.4.1beta/modules//lapack.dll':
  LoadLibrary failure:  The specified procedure could not be found.

I subsequently downloaded R-2.4.1beta from CRAN and had the same problem with
the contributed binary Rblas.dll

I haven't had any problems with the contributed binary up thru R-2.3.1.  I
checked the changes file and saw that for R-2.4.0 the Rblas.dll would have to be
recompiled, but also that the contributed binaries on CRAN had been updated. 
However, I couldn?t find any Rblas binaries with a date after 2005.  Any
suggestions on where to find an Rblas binary for WinXP and P4 chip, or do I need
to try to compile one on my own?

Thanks for any assistance,

Dan

I just looked into the one for P4 and it does export zdrot_ and works 
for me. Is your one from CRAN master?
