PL/SQL :: How To Find Error In Pkg Creation

I have 30 packages to be created for a new user, i call in the execute_pkg.sql which creates all the 30 packages.

i use like this

sql> set echo on
sql> set spool execute_pkg_spool.txt
sql>@execute_pkg.sql
sql> spool off

My questions:

I find it difficult to figure out the which pkg was not created, at present the spool file is too big with the pkg code in it

create or replace package test1....
...
..
..

Warning: Package Body created with compilation errors.

i wanted the output like this

test1
Warning: Package Body created with compilation errors.
