Near the end of the package you will probably see a Protect statement which
protects all the routine names against redefinition. Temporarily change that
cell so that it is not an initialization cell. Or if you are working with a
.m file, comment that statement out. Then you should be able to read in the
package again without all the error messages. When you finish, change the
statement back.
