Thanks very much for your reply!
Hmm, I'm using maxima 5.30.0, compiled from source, and I've byte-compiled
the emacs-lisp files in /opt/maxima-5.30.0/interfaces/emacs/imaxima, and
loaded imaxima.elc from that directory, but still the same error. And in
neither imaxima.el nor mactex.lisp can I find the variable TEX-MLABEL.
There is the line
MAXIMA::BETA-INCOMPLETE MAXIMA::TEX-MLABLE MAXIMA::BETWEENP
in sys-proclaim.lisp, but I don't know whether this has any bearing on my
error or not. And my .emacs file contains the line
(load "/opt/maxima-5.30.0/interfaces/emacs/imaxima/imaxima.elc")
to ensure loading of the correct file. I'm still a bit stumped!
cheers,
Alasdair
