[expert] libXt.a not found when relink oracle forms60

[Didier Festers]

Hello everybody.

Here is my problem:

I have installed Oracle Developer 6i on my new Mandrake 8 installation.
But ld can't find the libXt.a labrary during the relinking job.

I found on Suse it is in xdevel.rpm. 
But on Mandrake where and how can I find the rpm package containing this 
library?

Thank's for the help.
