Getting Ekiga up & running on Scientific Linux

It is not that hard, really...

You have to create a symlink once the install is done, in order to get the audio working (don't have a camera on my T60p to test that...)

 Unless you do that, you'll have no way of speaking, nor hearing anything while using Ekiga; all the audio devices are listed as SILENT (like that, with capital letters ;) )
Here are the steps, this is tested on a Scientific Linux 6.2 (32 bits) with all the updates installed as of today.

sudo yum install ekiga
cd /usr/lib/
sudo ln -s ptlib-2.6.5 2.6.5
