#aptitude install atlas3-base-dev

whereis libatlas.a
/usr/lib/libatlas.a   /usr/lib/libatlas.so

whereis libblas.a
libblas.a:

therefore, see below

do you mean that, as now located, these libraries are not seen by configure 
searching:

? and that I should do something else?

Apart from this, I was confused by, a couple of days ago:
#apt-file update
#apt-file search libatlas.a
atlas3-base-dev
while, after having installed atlas3-headers and mpich-shmem-bin, the above 
search command returns nothing (the same for libblas.a), and therefore my 
question that I had already posed. Even now after having installed the above 
packages.

Because apt-file search does not work "in my hands" (although apt-file is 
installed (as from #aptitude in admin main), I can not verify whether the 
last lacking piece of the cacke (libacml.a) is available from Debian. Perusal 
on internet 
(http://seldon.it.northwestern.edu/sscc/acmldoc/Linking_002fLinux.html) seems 
to indicated that the Linux 64-bit g77 version of ACML should be installed in 
the default directory, /opt/acml3.1.0/gnu64. Very likely I misunderstang but, 
anyway, I have installed g77 from Debian. Thanks for this clarification.
