Install KDE from unstable

[Gary James <gary_r_james@yahoo.com>]

I am trying to install KDE from the unstable branch onto Woody. When I apt-get kde or kdebase I get dependency errors. I think I have taced it down to a dependency for ksysguardd. When I 
try to apt-get ksysguardd the following line is displayed:

ksysguardd: Depends: libsensors-1debian1 but is not installable
E: Broken packages

Any thoughts on how to solve this. Also, I an new to Linux and Debian so particulars are appreciated.

Thanks,

Gary
