| Yes, this seems to be the current situation.  Actually, the packages in
| the alternations are not incompatible, much to the contrary, they all
| provide libblas-3.so and liblabpack-3.so through the alternatives
| mechanism.  In this case, my rant above is moot.

| and liblapack-3.so as in octave2.1:
| 
|     lapack3-dev | atlas3-base-dev | liblapack-3.so
|     refblas3-dev | atlas3-base-dev | libblas-3.so

Not sure. That is a question for Camm and not for me. I still seem to be
using

    refblas3-dev | atlas3-base-dev		

for R (where use an internal Lapack) and

    refblas3-dev | atlas3-base-dev, lapack3-dev | atlas3-base-dev

for Gretl.  So what you have above seems right to me, at least as far as
Build-Depends are concerned.

But as I said, if in doubt, ask Camm ...

| Another question: octave2.1-headers has also currently the following
| binary dependency:
| 
|     libhdf5-serial-dev | libhdf5-lam-dev | libhdf5-mpich-dev
| 
| These packages conflict with each other and this is a potential source of
| problems.  I do not know whether these packages are binary incompatible or
| not [hence the Cc: to Josselin.]

| Well, the other members are quite silent since this group has been

Well I do comment once every six months as, as we say, "talk is cheap".
Actual work is a different matter ...
