DOLFIN_VERSION is a #define (see src/kernel/main/dolfin/constants.h).
Yes sorry, the compiler actually says that the PACKAGE_VERSION variable
is
undefined.

I managed to compile and link everything (using default BLAS libraries
and
I still haven't checked if UMFPACK works), however I still have quite
big
problems since my code runs very slowly (compared to linux) and almost
gets stuck in the lump() routine because it takes ages.

Are you using uBLAS or PETSc? If you're using uBLAS, check the compiler
flags and make sure that you have -DNDEBUG. Otherwise, anything to do
with uBLAS will be dead slow.

Yes, thanks. It seems VS had the similar flag -NDEBUG which helped quite a
lot. I was also wondering if I could use some optimized BLAS like ATLAS.

DOLFIN doesn't use BLAS, but it may be used by libraries which DOLFIN uses, such as PETSc and UMFPACK. uBLAS doesn't use BLAS.

Is ATLAS independent from BOOST or do I need to have both installed?

It would be helpful if you submitted your fixes as an hg bundle (or a
series of small bundles, one for each set of fixes). I'm on parental
leave until the end of November so I have limited bandwidth, but
someone
else should be able to pick it up.
I signed up to the FEniCS wiki so that I'll be able to add a short
guide.
