Using sage-mode 0.6 with emacs21, I'm getting the
following parse errors (produced with 'emacs --debug-init')
on startup, i.e. when SAGE_ROOT/data/emacs/sage.el
gets loaded:

As far as I can see, the regular expression defining the
inferior-sage-prompt in sage.el causes the error. The syntax of
the line seems intact (number of opened/closed brackets, quotation
marks, ...). Alas, I'm not much of an elisp expert as to see the
problem here. Could be an api change in rx between emacs21
and emacs22 or something. The wrong-number-of-arguments
error message points into this direction (just guessing).
I got a report that with 'emacs22 --debug-init', there is no problem
showing and sage-mode can be loaded fine (thanks to dox_drum).
