| Thanks for spotting this problem.  Besides the gfortran vs g77
| incompatibility, I see other dependencies that can also cause problems:
| 
|     refblas3-dev | atlas3-base-dev
|     lapack3-dev | atlas3-base-dev
|     libhdf5-serial-dev
| 
| The first two are problematic because of the alternation.  If Octave is
| build with, say, refblas3-dev then mkoctfile will fail if the system
| contains only atlas3-base-dev, even though octave2.1-headears could be
| happily installed.

No, as they all provide the virtual package "libblas.so.3" that the Depends:
is really on, as per the shlibs files.  (Unless Camm changed that
recently...)

| The dependency on libhdf5-serial-dev is problematic because it is
| versioned in Build-Depends.  It should also be so for octave2.1-headers. 
| 
| I am inclined to change both the Build-Dependencies and the binary
| dependencies for octave2.1-headers to the following:
| 
|     refblas3-dev
|     lapack3-dev

Whenever you contemplate a change here, *please* run it by Camm first, and
have patience to wait a day or two for his reply. Well worth it, in my
experience :)

|     libhdf5-serial-dev (>= 1.6.4)
|     
| I hope the other members of the Debian Octave Group will comment on this.

Sure thing. :)
