Looks like the path to the blas library is missing completely. Will have to look at Makefile.am
I forgot to ask. Output of pkg-config --libs blas as we talked about on irc.
in ./configure --prefix=/home/gnuke/gentoo/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/home/gnuke/gentoo/usr/share/man --infodir=/home/gnuke/gentoo/usr/share/info --datadir=/home/gnuke/gentoo/usr/share --sysconfdir=/home/gnuke/gentoo/etc --localstatedir=/home/gnuke/gentoo/var/lib --libdir=/home/gnuke/gentoo/usr/lib/lapack/reference --with-blas=-lblas It should have ended with: --with-blas="-L/home/gnuke/gentoo/usr/lib/blas/reference -lblas" or something like that. Similar to what we did with Martin for linbox. It would be interesting to have the content of: /home/gnuke/gentoo/usr/lib/blas/reference/blas.pc
