I have built emacs on one Solaris machine under my home directory and
attempted to run it on another.  It dies like this:

Warning: arch-independent data dir (/usr/local/share/emacs/23.0.91/etc/)
does not exist.
Error: charsets directory (/usr/local/share/emacs/23.0.91/etc/charsets)
does not exist.
Emacs will not function correctly without the character map files.
Please check your installation!
Fatal error (11)Segmentation fault (core dumped)

I suspect the warning are a bit of a red-herring because they do not
existing on the build machine either.  Unfortunately, I cannot debug
emacs on the run machine.  However, pstack tells me:

They should be on the build machine, they are in the emacs source tree,
in emacs/etc/charsets.

What I meant is that they are not on the build machine _in the
directories_ that Emacs says it expects to find them.  (As I implied, I
do not install pretests, I run them from where I build them.)  Since
Emacs does not crash when run on the build machine, I figure that the
warnings are misleading.

At the very least, Emacs should not coredump.  Emacs 22.3 doesn't
coredump.

I built the pretest 23.0.91 under my home directory on
machine A, and ran it on machibe B which mounts the same
home direcotory, but Emacs starts up normally.  The value of
the variable data-directory is
"/home/handa/emacs-23.0.91/etc/".

Next, I moved etc/charsets to etc/charsets.tmp and ran Emacs
on machine A and B.  In both cases, this message was shown.

Error: charsets directory (/home/handa/emacs-23.0.91/etc/charsets) does not exist.
Emacs will not function correctly without the character map files.
Please check your installation!

So, the shown directory is the correct place.

I fixed it.  Now even if Emacs can't find etc/charsets,
Emacs can be used at least for handling ASCII text.
