I am trying to use the umfpack that came with petssc. Petsc is configured
as follows:
./config/configure.py --with-mpi-dir=$INSTALL_PATH --with-clanguage=cxx
--download-hypre=yes --enable-hypre=1 --download-umfpack=yes
--enable-umfpack=1 --enable-shared=1

What options do I need to give to scons? I tried setting the variable
UMFPACK_DIR to
$PETSC_DIR/externalpackages/UMFPACKv4.3/linux-gnu-cxx-debug/UMFPACK

I also tried to add
$PETSC_DIR/externalpackages/UMFPACKv4.3/linux-gnu-cxx-debug/UMFPACK/Lib to
LD_LIBRARY_PATH, still without success (Anders thought this wasn't
necessary as petsc was configured with enable-shared). I keep getting a
linking error when running the package config generator:
umfpack_config_test_lib.o: In function `main':

Running 'ar t' on libumfpack.a indicates that it is available. Any hints?
