Skype is a piece of software bringing free internet telephony to us folks.

From fresh Amigo 2.0 install:

Download:
skype_staticQT-0.92.0.12.tar.bz2 (from www.skype.com)

Unpack:
bzip2 -d skype_staticQT-0.92.0.12.tar.bz2
tar xvf skype_staticQT-0.92.0.12.tar

Dependencies:
from Slack CD1 in /slackware/l directory:
installpkg aumix*.tgz
installpkg amp*.tgz
installpkg gtk+2-2*.tgz
installpkg atk*.tgz
installpkg pango*.tgz

from Slack CD1 in /slackware/x directory:
installpkg xfree86-fonts-100dpi*.tgz
installpkg xfree86-fonts-cyrillic*.tgz
installpkg xfree86-fonts-scale*.tgz

Now, configuration of sound:
I use OSS and my soundcard is Yamaha PCI something, so i edited /etc/rc.d/rc.modules and added this line:
/sbin/modprobe ymfpci

Started 'aumix' to adjust mic and speaker volume.

Now, change directory to 'skype_staticQT-0.92.0.12
enter './skype' to launch application

Register yourself as a skype user, and find someone to call.

This works for me.

BTW: amp is not a dependency, you can use amp to play a mp3 file to test sound (amp <name of mp3 file>)

Excellent! Skype is already one of the excellent programs to be offered in AmigoXP or other upcoming versions.
Should add that you also need glib2*.tgz from the /l directory. Could you dress up a HOWTO on upgrading Amigo -2.0 to gtk+2? Your mini-HOWTO'S are very easy to follow. Here's the link to the WIKI .GTK2 for Amigo2.0
