There is a binding to BLAS/LAPACK at http://www.isi.edu/~hdaume/HBlas/
but it might be too heavyweight for just calculating eigenvalues.
however, it should be fast :)

A standard matrix representation in the libraries would be nice. (not
necessarily all matrix operations, but a representation/type so different
peoples matrix libraries can play nice with each other)
I was thinking something like a general matrix type, which a class for things
that can be converted too it, and another class with a partial function
for converting the general matricies to specific implementation
versions. (so that one can write a library only for square
matricies for instance and still use the general conversion routines)
But I am sure others have given this more thought...
