Check the settings in
(getenv "PATH")
and
exec-path

Personally, I use

(defun TeXlive (year)
  "Use TeXlive with the given year (given as string), nil if no TeXlive."
  (interactive
   (let* ((year
           (directory-files "/usr/local/texlive/" nil "\\`[0-9]+\\'")))
     (setq year
           (completing-read (format "Year to use (default %s): "
                                    (car (last year)))
                            (cons "none" year)
                            nil t nil nil (car (last year))))
     (list (unless (string= year "none") year))))
  (let ((path (getenv "PATH")))
    (while (string-match "/usr/local/texlive/[0-9]+/bin/i386-linux:" path)
      (setq path (replace-match "" t t path)))
    (when year
      (setq path (format "/usr/local/texlive/%s/bin/i386-linux:%s"
                         year path)))
    (setenv "PATH" path)))

to select one of several TeXlive installations.  Apparently, exec-path
does not need setting here: at least I don't have problems without it.
