skype error

[Ivan Petrov <ipmmx@yandex.ru>]

I've installed skype 4.3 on my squeeze-64 with new libs copied from 
archive like here:
http://community.skype.com/t5/Skype-%D0%B4%D0%BB%D1%8F-Linux/Skype-4-3-%D0%B4%D0%BB%D1%8F-Debian-Squeeze-6-amd64/td-p/3554479

But when I tried to use it I've got error message:
skype: symbol lookup error: skype: undefined symbol: 
_ZN19QAbstractProxyModel11setItemDataERK11QModelIndexRK4QMapIi8QVariantE

What can be done with this?

I.P.
