[petsc-dev] Handling ESSL + Lapack and PESSL

[Tom Cortese]

On the large IBM systems at NAVO, there are some special libraries 
installed in addition to ESSL -- I have no idea if this is standard across 
AIX machines, or if this is something special that the center staff 
installed:

/site/lib: %ls
blas_PW5.a@              libblas_PW5_64.a@        libscalapack_PWR5.a@
blas_PW5_64.a@           libexpat.a               libscalapack_PWR5_64.a@
lapack_PW5.a@            libexpat.la*             libtermcap.a
lapack_PW5_64.a@         liblapack_PW5.a@         tmglib_PW5.a@
libblas_PW5.a@           liblapack_PW5_64.a@      tmglib_PW5_64.a@
/site/lib: %
