# to 'refblas3-dev|atlas3-base-dev' is changed to 'libblas-dev' to
# use the new gfortran-built BLAS libraries. From R 2.7.0, the
# dependency is on 'libblas-dev | libatlas-base-dev' for
# r-base-dev.

# 2. Starting with Debian packages for R 2.6.2, new build dependency
# on liblapack-dev to switch back to using Debian's Lapack rather
# than the version supplied by R. From R 2.7.0, the dependency is
