Red Hat 7.1 and rdiff-backup > 2.1

[Iván Renedo Chantres]

I use Red Hat 7.1 and i can only use 2.1 version of rdiff-backup. With the
newer versions, i get this error:

	File "/usr/bin/rdiff-backup ", Line 232
		if predicate(i): yield i

	Syntax error: invalid syntax

i have tried with differnts version of python, but the result is always the
same.
At the beginning of the rdiff-backup file i define the version of python.

If someone knows how to repare it, let me know.
Thanks
