Method Overrides Across Packages

[Jim]

I know I asked this before a long time ago and I can't seem to find the
answer.

In Delphi 4 I have a class with methods declared as virtual and I put
that class in package. I now create a new package with a descendent of
the first class. When I override the methods defined in the original
class D4 complains the method is not found in the base class. D5 to
D2007 all compile just fine.

What is the trick to make this work?

Thanks,
Jim
