except...

emacslispdir is supposed to be PREFIX/share/emacs/site-lisp

In case emacsetcdir is not set to anything else this is to be
the same.

But what is the value for emacsetcdir used in Gentoo ?
------------------------------------------------------

The above "/usr/share/emacs/24.0.90/etc/" is analogous to=20

PREFIX/share/emacs/<version>/etc;=20

In PREFIX/share/emacs/<version> there is also (23.a in question):
drwxr-xr-x. 11 root root  4096 May 31 13:49 etc/
drwxr-xr-x.  4 root root  4096 May 31 13:49 leim/
drwxr-xr-x. 23 root root 12288 May 31 13:49 lisp/
drwxr-xr-x.  2 root root  4096 May 31 13:49 site-lisp/

(this site-lisp is different than the emacslispdir in question, so
the 'etc' here doesn't match emacsetcdir... but hey! maybe the answer
to the above question is: PREFIX/share/emacs/etc ? )

Anyway, I'm for inclusion of this patch, provided that there is good
explanation of it -- It doesn't seem to break things.

indeed.
