Dear Dev,
BLAS and LAPACK are already included in the Quantum-ESPRESO distribution,
you don't need to install them separately. Nevertheless it is better to
use platform-specific high-performance libraries such as mkl (intel), acml
(amd), essl (ibm power), sun performance libraries (sun sparc). Or, at
least, the automatically-tuned open-source ATLAS libraries, which are a
bit difficult to compile, but can often perform as good as commercial ones.
In general, if you have problems with a specific library you should
contact the developers of the library itself, which are definitely more
experienced than us on the matter. Finally, this kind of libraries are
normally well known and widely used, hence a simple google search will
give you hundreds of help pages, addressing you very issue.
best regards
