Hi and thanks for the previous answers. I'm still going to need a bit of
help.

Unfortunately, I am not qualified enough to understand the above "patch".

Anyhow, the main conclusion was that there was a problem with include
path, e.g. boost/numeric/bindings/lapack/lapack.h: No such file or directory

So I downloaded the latest boost bindings
http://news.tiker.net/news.tiker.net/download/software/boost-bindings/boost-bindings-20080405.tar.gz

and ran
        ./configure
        make
        make install
from the extracted directory, which contains lapack.h.

However, this file is still not present in /usr/local/.../lapack/, only
lapack.hpp. Probably, here's the reason: the make file contains:

for header in `find boost -name '*.hpp'`; do \
          install -D $$header /usr/local/include/boost-bindings/$$header ; \
          done

What should I do from here?
