ply no longer python 2.3 compatible

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use lex and make sure the table file is written.

What is the expected output? What do you see instead?
Line 143 in lex.py: "basetabfilename = tabfile.rsplit(".",1)[-1]". In
python 2.3, the rsplit method doesn't exist. It is new in python 2.4.

What version of the product are you using? On what operating system?
I'm using 2.4 prerelease version on python 2.3.

Please provide any additional information below.
Maybe use a regular split, which reduces performance. Alternative, an
rfind() can be used.

Fixed by just changing rsplit(".",1)[-1] to split(".")[-1].

That's also a solution, although a slightly less efficient one, since it has to 
go
through the entire string...
