By default - if you use the same PETSC_ARCH and same download options - the installed packages won't get rebuilt.<br>
<br>
However - if you want to have  a single install of externalpackages shared across multiple petsc builds - its best<br>
to install externalpackages in a prefix location. And then use this for subsequent builds.<br>
<br>
./configure PETSC_ARCH=arch-pkgs --prefix=$HOME/petsc-pkgs --download-mumps --download-scalapack<br>
<br>
./configure PETSC__ARCH=arch-use-pkgs --with-mumps-dir=$HOME/petsc-pkgs --with-scalapack-dir=$HOME/petsc-pkgs<br>
<br>
<br>
--with-packages-search-path options hardly ever gets used - so will have to check if its broken or not.<br>
