I have a suggestion for the maxima mode in org-babel. I am using Emacs on a Mac which means that some hint work differently. The standard distribution of Maxima for the mac does not have a command 'maxima' anywhere on the path.
The way to start character mode maxima from a shell is using /Applications/Maxima.App/Contents/Resources/maxima.sh Maxima itself brings an emacs mode with the standard distribution, and in maxima mode for Emacs he maxima command can be configured by using (setq maxima-command "/Applications/Maxima.app/Contents/Resources/maxima.sh") in .emacs So it makes sense that maxima mode in org does (require 'maxima) and then uses maxima-command when it defines the function (defun org-babel-execute:maxima I hope this is a reasonable suggestion.
