[PD] Installing PD under Linux

[Normand Fisher]

Hi,
I just installed Linux for the main purpose of using PD under Linux.

However, when I try to install the pd rpm file under RH9, I get the following message:
"libtcl.so.0 is required by PD
 libtk.so.0 is required by PD"

As far as I know (not much I'm afraid) the libraries to TCL/TK have been installed as part of the default installation of RH9.

Is this a PD install or a RedHat install problem?

Could someone poit me in the right direction?

Thanks
Normand
