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?
Definitely it does not suffice to look in SAGE_ROOT/spkg/installed
''only'', which I just checked.
Do you think the following snipped would be fine for spkg-install?
{{{
SMALL_GROUPS=`cd $SAGE_ROOT/spkg/optional/;
$SAGE_ROOT/spkg/standard/newest_version database_gap`
if [ "$SMALL_GROUPS" = "" ]; then
SMALL_GROUPS=`cd $SAGE_ROOT/spkg/installed/;
$SAGE_ROOT/spkg/standard/newest_version database_gap`
if [ "$SMALL_GROUPS" = "" ]; then
echo "Failed to find SmallGroups library. Please install the
database_gap spkg"
exit 1
fi
fi
}}}
Regards,
Simon
