[Rd] proper link to ACML blas | compiling 2.9.0

[Evan Cooch]

Normally, I do the following to configure R for compilation on my 
Opteron box with ACML installed:

./configure --with-tcltk --with-blas="-L/opt/acml4.3.0/gfortran64/lib 
-lacml"

However, when I do so, and look at Makeconf, I see

BLAS_LIBS = -lblas

I thought I would see

BLAS_LIBS = -L/opt/acml4.3.0/gfortran64/lib -lacml

Why isn't Makeconf picking up the right BLAS_LIBS (or is it? does -lblas 
mean its finding the right blas?).

I tried

LD_LIBRARY_PATH=/opt/acml4.3.0/gfortran64/lib
export LD_LIBRARY_PATH

and then did a new Configure, but Makeconf still shows only

BLAS_LIBS = -lblas

When I look at config.log, I see a 'failure' that I think might be part 
of the story:

So, perhaps things go awry at this point...weird thing is, thee is no 
libgfortran.so.3 anywhere on the system that I can find....
