The package was in use. There are a couple of ways to find who is using a package at any given moment.

You can join v$session to dba_ddl_locks or you can use v$acess but you can see who is executing the package. The code cannot be recompiled while the code is in use.

It would have been nice if you had posted your query and results so we could make suggestions on how to improve the query or what you should check next.

Generally speaking if you submit a create or replace on a package and it takes longer than expected you can open a second session and query for usage. Depending on what you find determines your action.

If may be you just need to re-submit immediately or wait till a batch job completes. There could be a daemon (continuously running batch) job that you have stopped and re-started right after you make the change. It depends on your environment.
