pidgin-skype 20100121+dfsg-1 (i386 binary) in ubuntu lucid

 This protocol plugin allows libpurple to communicate with Skype.
 Applications using libpurple (Pidgin, Finch, Empathy/Telepathy,
 etc.) can thus show your Skype contacts alongside those from
 other protocols, and you can communicate with them using that
 application instead of the Skype user interface.
 .
 This plugin communicates with the Skype application in the
 background to perform its work, so it's necessary to have Skype
 installed and running.
 This product uses the Skype API but is not endorsed, certified
 or otherwise approved in any way by Skype.
