running emacs without installing

[Kin Cho]

Hi,

I want to run emacs on a machine X without first installing
emacs.

machine X already has NFS access to another machine Y which has a
normal emacs installation.

By setting LD_LIBRARY_PATH, the emacs binary on Y launches ok on
X, but then exits with these errors:

Warning: arch-dependent data dir 
(/usr/local/libexec/emacs/21.3/i686-pc-linux-gnu/) does not exist.
Warning: arch-independent data dir (/usr/local/share/emacs/21.3/etc/) does not 
exist.
Warning: Lisp directory `/usr/local/share/emacs/21.3/site-lisp' does not exist.
Warning: Lisp directory `/usr/local/share/emacs/site-lisp' does not exist.
Warning: Lisp directory `/usr/local/share/emacs/21.3/leim' does not exist.
Warning: Lisp directory `/usr/local/share/emacs/21.3/lisp' does not exist.
Cannot open load file: term/x-win

If I use softlink the missing paths above to machine Y's paths,
then emacs starts normally.

I want to avoid the softlink on machine X.  Are there environment
variables to tell emacs where to find the data and lisp dirs?

Thanks.
