I've added a couple of extra repos in my x86_64 Fedora 11 KDE installation.
Namely, skype and rpmfusion and no rawhide stuff.
I've asked then to install skype (Skype 184.108.40.206).
While I was expecting a lot of packages because skype has decided not to support 64bit environments, I have found some very weird packages within the 79 item list.
The full log of the yum installation process (yumlog.txt) is attached here.
I suspect some strange dependency, maybe just one or two items, that cause all this pulling.
