First of all i think it should go to octave mailing list rather than
to octave-forge
(cc accordingly).

Second, the lapack/atlas libraries on Fedora 11 and rawhide are suspect
(they are definitely broken on i386). Sometime ago somebody decided that
some files from lapack that should be compiled without optimization
(per lapack's docs) can be compiled with Os. This used to work for a while
but now gcc got more aggressive and breaks those on some platforms
(at least on i386 and may be on ppc).

Sincerely,

Dmitri.
