Here are the instructions on how to install skype on Moblin. These are actually for Fedora 10 but they work perfectly for Moblin.
step 1: create a file in /etc/yum.repos.d/ by the name skype.repo with the following contents
[skype]
name=Skype Repository
baseurl=http://download.skype.com/linux/repos/fedora/updates/i586/
gpgkey=http://www.skype.com/products/skype/linux/rpm-public-key.asc
enabled=1
gpgcheck=0
step 2: open a terminal and issue the following command as root user
$ yum install skype
After you do that you probably want Skype to show up in under your Applications. In order to do that navigate to /usr/share/applications/ and edit the skype.desktop file.
cd /usr/share/applications/
sudo vi skype.desktop
Then make the document look just like this:
[Desktop Entry]
Version=1.0
Name=Skype
Comment=Internet Chat
GenericName=Skype
Exec=skype
Terminal=false
X-MultipleArgs=false
Type=Application
Icon=skype.png
Categories=Network
Then hit "alt + :" to get out of the editing mode. Finally hit ":wq!" to save and quit vi. You may have to reboot at this point, but when you do Skype should show under applications in the internet section.
