Starting with about version 0.60 of Red Gnus, NoCeM stopped working
properly for me.  When it loads, I get the message that
gnus-article-save-directory is not defined, and the only way to make
it work is to forcibly load gnus-art and gnus-sum in my .gnus.el.
Require doesn't work.  Of course, both of these are being required by
gnus-nocem.el, so if require worked, I shouldn't get this error.  Do I
need to recompile something?

In addition, since about 0.60, gnus-article-prepare-hook is undefined
when I try to go into the summary for a newsgroup.  setting it to nil
seems to work.  I'm using tm7.88 and Mailcrypt 3.4, and both have been
recompiled with the version of Red Gnus I'm currently using (0.74).
Do I need to recompile something or what?

Note:  This happens with both Emacs 19.34 and XEmacs 19.14.  I am not
sharing any elisp files between them.

Here are my .gnus.el and .emacs files.
