Install skype 4.2 on a linux system without GLIBCXX_3.4.15

Install Skype 4.2 on OpenSuSE 11.4

(a system without GLIBCXX_3.4.15)
OpenSuSE 11.4 lacks GLIBCXX_3.4.15 (has GLIBCXX_3.4.14 only), while Skype 4.2 needs it.
You can verify which GLIBCXX you have installed with:
strings /usr/lib/libstdc++.so.6 | grep GLIBC

It is possible to install it anyway:

• Download Skype 4.2 for OpenSuSE 12.1 from [http://www.skype.com/it/download-skype/skype-for-linux/]
• Install skype ignoring the failed dependency warning
• Downlad libstdc++6-4.7.3_20130411-96.1.i586.rpm from [http://download.opensuse.org/repositories/devel:/gcc/openSUSE_12.2/i586/]
• Copy libstdc++6-4.7.3_20130411-96.1.i586.rpm in your ~/bin directory or somewhere else in your home
• cd ~/bin (or wherever you copied the rpm)
• Extract locally the rpm file with the command: rpm2cpio libstdc++6-4.7.3_20130411-96.1.i586.rpm | cpio -idmv
• Run skype from a terminal with the command: LD_LIBRARY_PATH=/home/yourname/bin/usr/lib/:/usr/lib/:/usr/local/lib/ skype

The method described here does not break any dependency nor install system libraries unsupported for your system.
