Another longish approach would be to set `process-environment', maybe
something like this in eval:

(let ((process-environment process-environment))
  (add-to-list 'process-environment
               "TEXINPUTS=.:..:../resources:../../resources:"))

But I think this is a kludge anyway.  It is probably easier not to mess
with environment variables within Emacs and make it all happen outside
Emacs.  Maybe a symlink to the relevant directory below $TEXMFHOME?
