Actually I was misleading you, I'm using ACML, not MKL. We have both
MKL and ACML available, and I tried both; in the end I think I stuck
with ACML because it was showing slightly better performance for
certain operations.

My configure line is

INCLUDE="-I/apl/octave/include -I/apl/hdf5/hdf5-1.6.6/include
-I/usr/X11/include"
./configure F77=ifort FFLAGS="-O3 -xW" \
CC=icc CFLAGS="-O2 -xW $INCLUDE -mieee-fp" \
CXX=icpc CXXFLAGS="-w -O2 -xW $INCLUDE -mieee-fp" \
CPP="icc -E" CPPFLAGS="$INCLUDE" \
CXXPP="icpc -E" \
BLAS_LIBS="-L/apl/acml/acml/ifort64_mp/lib
-Wl,-rpath=/apl/acml/acml/ifort64_mp/lib -lacml_mp -lacml_mv
-L/apl/intel/fc/11.0.074/lib/intel64 -lifcoremt -liomp5 -lpthread" \
LDFLAGS="-L/apl/octave/lib -Wl,-rpath=/apl/octave/lib
-L/apl/hdf5/hdf5-1.6.6/lib -Wl,-rpath=/apl/hdf5/hdf5-1.6.6/lib" \
--prefix=/apl/octave --disable-extra-warning-flags --disable-docs

modifying this for MKL involves just adjusting the BLAS_LIBS variable.
