Yes, you can! Here is an extract of the FreeBSD port's Makefile:
.if defined(WITH_ATLAS)
LIB_DEPENDS+= atlas.2:${PORTSDIR}/math/atlas
LIBBLASLAPACK= "-L${LOCALBASE}/lib -lalapack -lf77blas -latlas -lm"
.else
LIB_DEPENDS+= lapack.4:${PORTSDIR}/math/lapack
LIBBLASLAPACK= "-L${LOCALBASE}/lib -llapack -lblas -lm"
.endif
CONFIGURE_ARGS+= --with-blas-lapack-lib=${LIBBLASLAPACK}
