Comment (by SimonKing):
For the following test, I added the command "bla" into cohomology.pyx,
right after "import os". The attempt to install the resulting spkg was
reported to be successful, even though of course there is an error:

So, perhaps this is not a problem of my script but a problem of the script
of Sage that is called by "sage -i".
