>Description:
When EMACS_TYPE=emacs23nox and one attempts to install certain packages (for 
the sake of example, let's say mail/wl-snapshot), the emacs batch command does 
not have the correct load path resulting in failed compilation as so:

==========================================================================
The following variables will affect the build process of this package,
wl-2.15.9.20110420.  Their current value is shown below:

        * EMACS_TYPE = emacs23nox
        * SSLBASE = /usr
        * SSLCERTS = /etc/ssl/certs
        * SSLDIR = /etc/ssl
        * SSLKEYS = /etc/ssl/private

Based on these variables, the following variables have been set:

        * EMACS_BIN = /usr/pkg/bin/emacs
        * EMACS_ETCPREFIX = /usr/pkg/share
        * EMACS_FLAVOR = emacs
        * EMACS_INFOPREFIX = /usr/pkg/info
        * EMACS_LISPPREFIX = /usr/pkg/share/emacs/site-lisp
        * EMACS_PKGNAME_PREFIX (defined, but empty)
        * EMACS_VERSION_MAJOR = 23
        * EMACS_VERSION_MICRO (defined, but empty)
        * EMACS_VERSION_MINOR = 3

You may want to abort the process now with CTRL-C and change their value
before continuing.  Be sure to run `/usr/pkg/bin/bmake clean' after
the changes.

The issue here is that EMACSLOADPATH, as defined in editors/emacs/modules.mk, 
isn't complete enough for emacs to locate the required dependencies and thus 
fails.

Currently, this impacts the following packages:

 - devel/flim
 - devel/semi
 - inputmethod/skk
 - mail/wl-snapshot

Probably more I haven't checked.
>How-To-Repeat:
1) Remove any prior version of emacs installed via pkgsrc

2) Edit /usr/pkg/etc/mk.conf and set EMACS_TYPE=emacs23nox

3) Attempt to install devel/flim (emacs-nox11 v23.4 will be installed)

Building of package will fail as so:

/usr/pkg/bin/emacs -batch -q -no-site-file -l FLIM-MK -f compile-flim NONE NONE 
 NONE
Warning: Could not find simple.el nor simple.elc

/Volumes/TempStorage/pkgsrc-2012Q2/devel/flim/work/flim-1.14.9/FLIM-ELS...
Cannot open load file: advice
*** Error code 255

>Fix:
A temporary workaround is do invoke bmake as follows:

 $ cd path/to/package (e.g., /usr/pkgsrc/devel/flim)

 $ bmake 
EMACSLOADPATH=$PWD/work/.buildlink/share/emacs/site-lisp/:$PWD/work/.buildlink/share/emacs/23.4/lisp/:$PWD/work/.buildlink/share/emacs/23.4/site-lisp/
 install

A longer term solution would be to fix how EMACSLOADPATH is defined in 
editors/emacs/modules.mk.  One clue to fixing the issue can be found at 
http://www.ki.nu/~makoto/diary/2012/03/06/1.html although be warned that the 
provided patch found at 
http://www.ki.nu/~makoto/diary/attach/2012/20120306-emacs-modules.mk-diff did 
not work for me :/
