Two different glibc versions on the same machine

[Vitaly A. Repin]

Hello!

Problem:  There is a linux system with glibc 2.2.5.
I want to run skype application on this system.  
But it requires glibc 2.3.2.  

That's why I try to install and run glibc 2.3.2 (for skype) and 
glibc 2.2.5 at the same time.  Is it possible?

I've tried the following: 
1) unpacked glibc 2.3.2 compiled binary from rpm to the dir <dir>
2) set LD_LIBRARY_PATH to <dir>

But when I run the skype application in such environment I see 
segmentation fault and nothing else.

Can anybody help me with this problem?

Thank you beforehand & good bye!
