Well, like it says, take a look at config.log. Lapack 3.1.1 is installed, according to rpm -qa, but maybe libblas is missing, or maybe none of libf2c/libg2c/libgfortran can be found? liblapack is not usable without libblas, and the lapack+blas combination in turn is useless without a basic fortran library. On recent Fedora I'd expect that to be libgfortran.so; on older systems it was libg2c.so, and on even older systems, libf2c.so.
