None that I know of.

About the rk function, it was introduced after 5.9.3. (If you have time
you might try to encourage the maintainer of the Maxima package
for Ubuntu to update the package ....) You can get the code (2 files) here:
http://maxima.cvs.sourceforge.net/maxima/maxima/share/contrib/dynamics
and the documentation here:
http://maxima.sourceforge.net/docs/manual/en/maxima.html

Hope this helps,
