It _is_ loaded; it returns `t'.

I know that, that's why I never ever compile my config files -- because
I've been hit quite a couple of times but that problem in the past, and
because the startup time of my Emacs/Gnus is already very decent now (in
the order of 1 to 3 seconds).

As I said, what's un-understandable right now, is that my config _works_
with Emacs 24.5 and (the exact same) does not with Emacs 25.

The problems you point to (possibly missing package or use of
a compiled, not up-to-date, config file) couldn't explain that fact.

Both versions of Emacs read my `~/.gnus' file and load the `bbdb-gnus'
library found at `~/.emacs.d/elpa/bbdb-20140830.2031/bbdb-gnus.elc'.

To add more data points, here is a comparison of what's displayed in the
`*Messages*' buffer for both sessions:

- With Emacs 24.5:

Note that I've prefixed the lines which are different with a ">".

Best regards,

PS- I also have a problem with Gmane in Emacs 25.0, but I didn't look
    into that yet.
