Well, is umfpack.h in either /usr/include/ufsparse or
/usr/include/ufsparse? If not, it is probably something wrong with your
umfpack.pc. What you can do, is to run the UMFPACK pkg-config generator
script manually and look for any errors. That is, from the root of the
DOLFIN source tree, run

  python scons/simula-scons/simula_scons/pkgconfiggenerators/umfpack.py

This will generate a pkg-config file for UMFPACK in the current directory.
Does it differ from the one you have under /usr/local/lib/pkgconfig? If it
does, you should probably remove /usr/local/lib/pkgconfig/umfpack.pc and
run scons to generate a new one.
