All too true. If you /do/ feel game to try running two glibc versions, 
though, it is often possible. You would need to install the extra one in 
  a special directory in /usr/local, say /usr/local/glibc-320. Building 
from source and using './configure --prefix=/usr/local/glibc-320' would 
be the easy way to do so. You then add it to your LD_LIBRARY_PATH before 
running your special app, or use a wrapper script to do it for you. For 
example:

#!/bin/sh
LD_LIBRARY_PATH=/usr/local/glibc-320:$LD_LIBRARY_PATH \
   /usr/local/bin/appname

Naturally you'd replace '-320' with your chosen glibc version, I've just 
picked 3.2.0 as an example.
