Transmission 0.81 depends on a lot of my updated packages. gtk, pango, cairo, so on, can't tell at the moment. I decided that will no longer produce packages for the unmodified beta3, as there are LOT that simply cannot be compiled for such old package versions AND besides this - my beta3 IS customized, which means that for me to compile anything, i have to install plain beta3, which is unacceptable for me. Have to work with it.
Transmission's GTK front-end is called transmission-gtk. Run it through console and if you cannot manage to fix the errors, please PM me, so we don't flood here.
Pidgin WORKS on my modified beta 3, not pdaxii13 - I don't use it. If any errors - please tell me what you get, so we can solve it.
