download that spkg and install it from the downloaded version (that is,
using "sage -i path_to/database_gap-4.4.10.spkg" rather than "sage -i
database_gap-4.4.10", which downloads the file), then its installation is
recorded in SAGE_ROOT/spkg/installed, but not in SAGE_ROOT/spkg/optional,
which is where your spkg-install looks.

presence of the database is more or less copied from the Developer's
Guide. So, do you think I should look in both locations?
I think the one in the Developer's Guide is checking for something in
spkg/standard, which ought to be, well, more standard. When checking for
optional packages, maybe more care is needed? Anyway, the code snippet
looks okay to me. It should be easy enough to test.

database_gap.

These sound good to me.
