[R] Problems using external BLAS

[Bjørn-Helge Mevik]

I have problems building R 2.11.1 with an external BLAS.  I've tried
several with several libraries:

# ACML:
export LD_LIBRARY_PATH=/site/VERSIONS/acml-3.6.0/gfortran64_int64/lib
BLAS=--with-blas="-L/site/VERSIONS/acml-3.6.0/gfortran64_int64/lib -lacml"
LAPACK=--with-lapack

# MKL 11:
BLAS=--with-blas="-L/site/VERSIONS/intel-11.1/mkl/lib/em64t -lmkl_gf_lp64 -lmkl_sequential -lmkl_lapack -lmkl_core"
LAPACK=--with-lapack

# MKL 8.1, trad. way:
BLAS=--with-blas="-L/site/intel/cmkl/8.1/lib/em64t -lmkl -lvml -lguide -lpthread"
LAPACK=--with-lapack

I configure R like this:

export CFLAGS="-O3 -mtune=opteron"
export FFLAGS="-O3 -mtune=opteron"
export CXXFLAGS="-O3 -mtune=opteron"
export FCFLAGS="-O3 -mtune=opteron"

./configure --prefix="/site/VERSIONS/R-2.11.1" \
  "$BLAS" "$LAPACK" \
  --enable-R-shlib

In all cases, I get

configure:29120: checking whether double complex BLAS can be used
configure:29206: result: no

The conftestf.f and conftest.c seem to compile fine, but exit status
from conftest in line 29181 of configure is nonzero.

This is on a Quad-Core AMD Opteron node running CentOS 5.2, with gcc and
gfortran version 4.1.2 20071124 (Red Hat 4.1.2-42)

(I have also tried without the *FLAGS variables, and without
--with-lapack.  The result is the same.)

(We have successfully built older versions of R with MKL 8.1 earlier, but
with intel compilers v. 10.1, using
./configure --prefix="/site/VERSIONS/R-$version" \
  --with-blas="-L/site/intel/cmkl/8.1/lib/em64t -lmkl -lvml -lguide -lpthread" \
  --with-lapack="-L/site/intel/cmkl/8.1/lib/em64t -lmkl_lapack64 -lmkl" \
  --enable-R-shlib
but we wanted to switch to gcc because not all R packages compile with icc.)

Does anyone have any idea about what could be wrong?
