Debian Wheezy 64 bit: installing correctly skype

I assume you've downloaded skype from site.
The Debian 7 multiarch package.

I have some problem during skype installation on my 64 bit architecture.
Something like this:

package architecture (i386) does not match system (amd64)
Errors were encountered while processing:
skype

So, I need to do these steps:

dpkg --add-architecture i386
apt-get update
apt-get install qt-at-spi:i386
dpkg -i  skype-debian_4.3.0.37-1_i386.deb
(where skype-debian_4.3.0.37-1_i386.deb is the file version I currently downloaded..)

Now It goes like a charm....

Bye...
