DBMS_DEBUG is used for debugging a PL/SQL program during execution and not compilation. Right tool, wrong situation :) When a package is being executed, it cannot be compiled. Any attempts to compile it will force the session to 'hang' on the 'library cache lock'. What the Oracle tech suggested was a brute force method of killing all procs that were holding the pin on the package. These sessions holding the pin can easily be identified using a wrapped PL/SQL package called 'who_is_using' - take this off MetaLink for your version. You should then be able to selectively kill off those sessions before compiling the package.
