# 32766. This logic attemps to import the sqlite3 bindings and determine whether
# the version of the installed SQLite version is greater or equal to 3.32. If
# the sqlite3 bindings cannot be imported (either because they aren't installed)
# or because the platform is using SQLite 1 or 2 then it falls back to the
# 999 value.
