Error in Compiling a Wrapped Package Body

I am having a wrapped package body..and it is in uncompiled state.. I am not able to compile that Package.. also I am having same package available on other schema which is in compiled state.. Is there a way to bring that compiled packege to the schema where my uncopiled version of package is lying.. Also I am not able to make any changes in uncompiled version of Package..

how about finiding out why it wont compile and fix it?

Assuming you have no clue about what the packages does... just compare both schemas looking for what's different.
