thanks, that helps and it gets past the point where it froze before. However, now it complains that PETSc needs the chaco package. I had removed the --download-chaco option from the PETSc build, if I add it back in, I get

=============================================================================== TESTING: check from config.libraries(config/BuildSystem/config/libraries.py:146)*******************************************************************************
UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log for details):
-------------------------------------------------------------------------------
You cannot use Chaco package from Sandia as it contains an incorrect ddot() routine that conflicts with BLAS
Use --download-chaco
