[PD] does anybody know why Ubuntu 10.10 wants do remove pd-extended?

[Matteo Sisti Sette]

Hi,

I'm upgrading from Ubuntu 10.04 to 10.10 (something i've just found out 
is possible the option being simply hidden by default).
During the upgrade process, the system decides that some of the 
installed packages have to be removed. For some reason one of them is 
pd-extended.

I wonder if anybody knows why pd-extended needs to be uninstalled when 
upgrading to 10.10... just curious.

Thanks
m.
