[R] Trouble configuring R to use ACML

[Prof Brian Ripley]

This is easier if you simply link to the ACML BLAS as an alternative 
to Rblas.so -- see the R-admin manual.

If you need further help, please ask on the R-devel list (see the 
posting guide).  It seems likely that you missed the comment in the 
R-admin manual about ensuring that the ACML lib directory is in 
LD_LIBRARY_PATH, so please check the manual subsection carefully. 
(More generally, you may well need to add that directory to the ld.so 
cache: some installation of ACML arrange to do so, some do not.  I 
have

gannet% cat /etc/ld.so.conf.d//acml-x86_64.conf
/opt/acml4.4.0/gfortran64/lib
/opt/acml4.4.0/gfortran64_mp/lib
.)
