It looks like that g-ctan always updates its package DB on some commands. IMHO, this is overkill and time consuming, as most people would tolerate a some-days-old DB in favour of faster operations. I suggest to provide an option for max DB age, that, when expired, triggers automatically a DB update on relevant commands. F.i.
DB_MAX_AGE=7d # default 7 days
DB_MAX_AGE=1m # 1 month
Please provide the installed version of g-ctan by commenting
`emerge -pv g-ctan`, thanks.
The package has been removed.
