Why do you copy the complete gnus-sum.el when you just want to
change one function?  As a result, you won't see any future changes of
gnus-sum.el (bugfixes and new features).

What do you want to change exactly?  Oftentimes, a simple advice will do
without having to override the complete function.

Indeed, if Nikolaus copied both gnus-sum.el and gnus-sum.elc into his
other directory, then modified gnus-sum.el but didn't recompile it, and
additionally `load-prefer-newer' is nil, that would explain the issue.

It's `list-load-path-shadows'.
