Unfortunately I have never used OS X. Maybe someone on the 
lapackpp-devel mailing list can help here?

Well, you obviously have to get the LAPACK (without ++) library from 
somewhere. Usually it is clearly noted when lapack belongs to some other 
package, so I suppose it doesn't belong to that "Vector framework". You 
can also try to install LAPACK yourself http://www.netlib.org/lapack/
