printing Cups Gutenprint

[n dhert]

I updated the ports :
gutenprint-base-5.2.4_2             <   needs updating (index has 5.2.7)
gutenprint-cups-5.2.4_2             <   needs updating (index has 5.2.7)
now printing a text file
$ lp testfile.txt
doesn't print and
$ lpstat -t
says:
printer psg is idle.  enabled since Tue Oct 18 08:55:19 2011
        The PPD version (5.2.4) is not compatible with Gutenprint 5.2.7.
the file remains in the queue until it cancel it

How to solve?
There was nothing about that in /usr/ports/UPDATING ...
