eapply is a generic defined in base, but the method for bimaps (which
the GO object extends) is defined in AnnotationDbi. So...

Likely your global environment has AnnotationDbi on its search() path
(you loaded AnnotationDbi, or one of the packages you've loaded has
AnnotationDbi in the Depends: field of their name space). In contrast,
inside your package, AnnotationDbi is likely NOT imported, and hence
not on the search path used by the name space. So...

Your name space has access to 'base' by default, but not AnnotationDbi
& it's methods. When import the *db packages above you import the
maps, but not the methods that operate on them.
So what you need, I think, is
importMethodsFrom(AnnotationDbi, eapply)
with perahps other functions listed after eapply.

These differences are likely because verrsions of 'mode', 'summary',
etc `work' on AnnotationDbi objects, but of course give the
information the base version is supposed to give. The in-R versions
are finding the AnnotationDbi-defined methods. This is a variant of
your original problem.
Hope that helps, and is not too misleading.
