The main problem with these libraries as included with Fedora Core 3 was 
that some optimizations in GCC (version 3.4.2) caused them to not work 
at all. The fix is a change in compiler flags. The RPMs at Dmitri's ftp 
server are ones he put there from RHEL, but other updated versions are 
available from the "development" tree of the Fedora download server. 
There have been several threads on this and the other octave lists in 
the last few months, usually regarding some linear algebra function 
(eig, svd, etc.) going into an infinite loop and not returning, all of 
which have been caused by this problem. For more specific information, 
see the recent bugs filed on RedHat's bugzilla related to lapack (there 
are at least 2-3 of them IIRC). Compiling blas and lapack on Fedora Core 
4 should be interesting because GCC 4 is the default compiler--I haven't 
tried it yet.
