The "Internal error in regular expression engine" occurs also
in Python 2.4.0 when creating a regular expression containing
more than 9999 or's ("|").Dennis Benzinger wrote:

Are you still using Python 2.1?
In every later version you don't need the "from __future__ import nested_scopes" line.
So, if you are using Python 2.1 I strongly recommend upgrading to Python 2.4.1.

It all works well for rule count up to 800+ but when my replacement rules swells up to 1800+, it gives me a runtime error that says "Internal error in regular expression engine"... traceable to "return self.regex.sub(self, text)" in substitute() method.

I didn't read your code, but this sounds like you have a problem with the regular expression engine being recursive in Python versions < 2.4.
Try again using Python 2.4 or later (i.e. Python 2.4.1). The new regular expression engine is not recursive anymore.
