SQL & PL/SQL

I have a working instance of a commercial product based on an Oracle database. I exported the main schema of the database. I then created a new database with identical tablespaces and users as the original. After importing the .dmp file I found that everything works fine with the exception of a single package body that will not compile due to errors. Unfortunately the code is wrapped so I am unable to view the errors. Considering I have identical tablespace and user characteristics between the two databases, and that I imported the entire main schema owner, would it be correct to assume that the errors in that package must therefore be due to missing objects of other schemas (that were not imported)?
