APEX Builder Installation error : ORA-00054: resource busy

While installing APEX builder in a duplicated database, I receive the following warnings and errors;

The installation continues, however, the side effects of the above missing objects are numerous.
Once the pages are loaded and the installer puts me back in the console, I notice a number of invalid objects in the apex schema.

It seems that during the Team Development object installation, a resource busy issue compromises the installation. The solution was not an entire re-installation but rather
a re-running of the problematic subset of the installer - manually - and chasing it up with a recompile.

The script that runs the Team development install is <APEX_SOURCE>\apex\devins.sql

Within the devins.sql script, I extract the following lines of script and rerun them manually as sysdba:

alter session set current_schema = APEX_040200;

prompt Installing Team Development objects
@./core/team_tab.sql
@./core/wwv_flow_team.sql
@./core/wwv_flow_team_api.sql
@./core/wwv_flow_team_gen_api.sql

I then run a recompile:
@?/rdbms/admin/utlrp

The APEX objects are valid again and the builder is accessible.
