Many thanks Chris, I succeeded in building it.

The configure command above contained two problems that I had to correct
to get it to work though. 

In case other people are trying this, I used:

../configure -b 32 -D c -DPentiumCPS=1800 -Fa alg -fPIC
--with-netlib-lapack=/home/your-user-name/build/lapack/lapack-3.2.1/lapack_LINUX.a

That is (in addition to the different -b switch for my 32-bit machine
and the different processor speed): the dash before "alg" should be
removed, and "Lapack_LINUX.a" should be "lapack_LINUX.a".
