X$KGLOB not visible

On trying to compile a package body, I am getting the following error:

LINE/COL ERROR
-------- -----------------------------------------
23/7     PL/SQL: SQL Statement ignored
23/48    PLS-00201: identifier 'X$KGLOB' must be declared

In order to have a user "recognize" X$KGLOB, you have to either:

• Create a public synonym for the X$KGLOB in SYS and grant select on X$KGLOB to PUBLIC.

• Have the user create a private synonym for sys.X$KGLOB after SYS granted select on X$KGLOB to the user.
