Got skype 4.1 to work again here, just unpacked the binary archive over
the existing files, don't know what went broken or how..

FYI, I've made a list of the packages showing from a `ldd skype`, this
may indicate what you need to install, at least (here: CentOS6.3 up-to-date,
epel repo enabled):

 dbus-libs-1.2.24-7.el6_3.i686

 libXScrnSaver-1.2.0-1.el6.i686
 libXtst-1.0.99.2-3.el6.i686
 libXv-1.0.5-1.el6.i686
 openssl-1.0.0-25.el6_3.1.i686
 pulseaudio-libs-0.9.21-14.el6_3.i686
 pulseaudio-libs-glib2-0.9.21-14.el6_3.i686
 sqlite-3.6.20-1.el6.i686
 tcp_wrappers-libs-7.6-57.el6.i686
 zlib-1.2.3-27.el6.i686

Of course there may have indirect dependencies, but yum would tell you
that in time.

Important: I also have a full Qt 4.7 32-bit in /usr/lib/qt47, on which
my installed skype version depends on:
 libphonon.so.4
 libQtCore.so.4
 libQtDBus.so.4
 libQtGui.so.4
 libQtNetwork.so.4
 libQtWebKit.so.4
 libQtXml.so.4

I was not sure if I got this specific Qt version installed for
GuitarPro6 (commercial) or skype, but my LD_LIBRARY_PATH points
to that dir and it can't using the Qt 4.6 or 4.8 versions installed
locally (install from one of those repositories: base, epel, rpmforge,
puias, atrpms).

For this Qt47, I downloaded the following RPMs:
 phonon-backend-gstreamer-4.7.2-1_18.el6.i686.rpm
 qt47-4.7.2-1_18.el6.i686.rpm
 qt47-config-4.7.2-1_18.el6.i686.rpm
 qt47-webkit-4.7.2-1_18.el6.i686.rpm
 qt47-x11-4.7.2-1_18.el6.i686.rpm

And installed *manually* their contents to /usr/lib/qt47.

This also requires tweaking a bit in /usr/lib/qt47/bin and /usr/bin
(it's safe towards system Qt versions, it's just about fixing the missing q* qt47 apps and making correct symlinks isolated in /usr/lib/qt47/bin):
See my /usr/lib/qt47/bin contents:
 qdbus -> ../../../bin/qdbus-qt47
 qdbusviewer -> ../../../bin/qdbusviewer-qt47
 qmlviewer -> ../../../bin/qmlviewer-qt47
 qtconfig -> ../../../bin/qtconfig-qt47
 qtconfig-qt47 -> ../../../bin/qtconfig-qt47


Let me know if you succeed or still miss something!
