I am trying to upgrade my numpy installation from 1.5.1 to 1.6.1 on Ubuntu 10.04. When I build, it doesn't seem to use the installed lapack libraries, but uses lapack_lite. After installation (which seems to complete without error), importing numpy fails with an error that it can't find libquadmath.so.0. Any ideas what might be wrong? Am I missing a dependent package somewhere? How can I force the build to use the installed lapack stuff? (installed via synaptic from the ubuntu debs) Numpy 1.5.1 builds and installs with no problems. -- Thomas K.
