locate works on an index of the filesystem, which needs to be rebuilt
when you add files. Of course you only really care about 'system' files
like libgfortran.

The index (database) is updated by updatedb(8): from
http://linux.die.net/man/8/updatedb,

   updatedb creates or updates a database used by locate(1). If the
   database already exists, its data is reused to avoid rereading
   directories that have not changed.

   updatedb is usually run daily by cron(8) to update the default
   database.

You should be able to find the equivalent on your system by saying 'man
updatedb'.

The 'daily' part probably relies on the Linux system being up all the
time, so (if the database isn't rebuilt when the system is booted) you
may need to do it by hand.
