Have you tried what happens if you put sage directory in your path?

 looking into the sage-texmacs plugin, there is a python file and a
"scm" file (probably written in guile.
it says:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;
;; MODULE      : init-sage.scm
;; DESCRIPTION : Initialize SAGE plugin

... Copyright stuff

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

(plugin-configure sage
  (:require (url-exists-in-path? "sage"))
  (:require (url-exists-in-path? "tm_sage"))
  (:launch "sage -python `which tm_sage`")
  (:tab-completion #t)
  (:session "SAGE"))

thats the code, but I don't know exactly how it works and what "sage"
and "tm-sage" is.

I had sage installed in /sage directory and made a symlink to it from /
usr/bin . So making a symlink can't be the real problem, but who knows
for sure. Unfortunantly I also have uninstalled my Texmacs build, so I
currently cant help you with testing :(. Maybe someone with more
knowledge about this interface is around ...

Good luck
Emil
