Ok, installation should be now as easy as installing these three .deb files in a row (simply download by click on them, and then start the installation by clicking in your Transfers window on the appropriate download).

I've mirrored all of the necessary files for convenience:

#1: http://n9.indigoblack.de/deb/libpurp...10.0_armel.deb

#2: http://n9.indigoblack.de/deb/telepat....0-1_armel.deb

#3: http://n9.indigoblack.de/deb/im-prov...tional-0.2.deb

If you wish to deinstall these later, simply go to
Programs -> Manage Programs -> im-providers-additional and select Deinstall.

Note: This will not remove your accounts, they will simply not show up anymore, if you install the package later again, they will appear.

Note2: If you experience any icon corruption in Accounts view, please restart
