I've fixed the problem, though I'm not quite sure what the problem was. I'm posting this in case someone runs into a similar issue.
The fix was to completely uninstall the "redundant" versions of the library (ATLAS, OpenBLAS, etc.) which I had installed to fix other issues. The initial versions of BLAS and LAPACK packaged with Ubuntu are sufficient. I ran a clean build and everything works as expected.
