Yes and no. Your described use case (2x2 and 3x3) is not well supported.
However, there is the experimental "numeric-bindings" library in the
boost-sandbox, that provides bindings against external libraries for
eigenvalue computations like lapack, ACML or MKL. But honestly, I would
try to avoid the dependence on such external libraries if all I want are
the eigenvalues of 2x2 and 3x3 matrices.

The library "eigen" (http://eigen.tuxfamily.org) may be for you, but you
may have the same dependency problem with it as with VXL/VNL. (I have no
idea why your project must get rid of dependencies on VXL/VNL, so I
can't tell whether your project will have the same problems with
"eigen".)
