------------------------+---------------------------------------------------
I'm getting lots of failures on a patched version of 4.3.4.alpha0 for many
files related to homology:
{{{
sage -t -long "devel/sage/sage/homology/delta_complex.py"
sage -t -long "devel/sage/sage/homology/cubical_complex.py"
sage -t -long "devel/sage/sage/homology/examples.py"
sage -t -long "devel/sage/sage/homology/cell_complex.py"
sage -t -long "devel/sage/sage/homology/chain_complex.py"
sage -t -long "devel/sage/sage/homology/simplicial_complex.py"
}}}
The ones involving simplicial_complex.py all report
{{{
OSError: [Errno 2] No such file or directory
}}}
See below for me detailed information. I think John deals with this sort
of thing, but I don't even know what to classify it as, so I've stuck it
on ''doctest''.
