[glade--]glademm installation

[alex riccini <alr rn libero it>]

Hello,
I've a problem installing glademm-0.6.2b-1.i386.rpm on RedHat 7.2.
When I launch kpackage I get an error:

error: failed dependencies:
	libstdc++.so.2.10   is needed by glademm-0.6.2b-1 

I've read that libstdc++.so.2.10 is also called 
libstdc++-3-libc6.2-2-2.10.0.so
so I have made a symbolic link but the same error message is shown...
What's wrong?

Alex.
