Hopefully this will help someone else.
I was given access to a bunch of AIX(6) boxes at work that didn't have
emacs and didn't have a compiler so I couldn't build emacs from
source.
I was able to find some binary RPM's for AIX at
http://www-03.ibm.com/systems/power/software/aix/linux/toolbox/rpmgroups.html
I used
* emacs-21.3-1.aix5.1.ppc.rpm
* emacs-el-21.3-1.aix5.1.ppc.rpm
* emacs-leim-21.3-1.aix5.1.ppc.rpm
* emacs-nox-21.3-1.aix5.1.ppc.rpm
Of course I couldn't install the rpms because I am a non-root user, so
I extracted the files from the rpms using rpm2cpio like so
rpm2cpio myrpmfile.rpm | cpio -idmv
I actually extracted them on a linux box because I didn't have
rpm2cpio on the AIX box.
Once they were extracted, I tarred everything up and moved it to a
directory on the AIX box that I had permissions to. I then tried to
run "emacs-nox."
It wouldn't run because these were binary packages and the standard
locations of the files were "built" into the binaries. It was looking
for the standard files at
/opt/freeware/share/emacs/21.3/.......
I was getting the following errors
Warning: arch-dependent data dir (/opt/freeware/lib/emacs/21.3/powerpc-
ibm-aix5.1.0.0/) does not exis\
t.
Warning: Lisp directory `/opt/freeware/share/emacs/21.3/site-lisp'
does not exist.
Warning: Lisp directory `/opt/freeware/share/emacs/site-lisp' does not

Warning: Lisp directory `/opt/freeware/share/emacs/21.3/leim' does not
exist.
Warning: Lisp directory `/opt/freeware/share/emacs/21.3/lisp' does not
exist.
but of course I didn't have permission to install it there as a non-
root user. I had installed it in
/home/myuser/emacs/opt/freeware/....
After some searching, I found that I could set some environment
variables to override the default locations of the files. Here are
the variables I set.
EMACSLOADPATH=/home/myuser/emacs/opt/freeware/share/emacs/21.3/lisp
EMACS_DIR=/home/myuser/emacs/opt/freeware/share/emacs/21.3
EMACSDATA=/home/myuser/emacs/opt/freeware/share/emacs/21.3/etc
and exported them
export EMACSLOADPATH EMACS_DIR EMACSDATA
I could then successfully start emacs-nox on the AIX boxes. Ahhhhhh
Hope this helps someone else avoid a slow painful death by vi.
