RPM Upgrade

[Shawn Michael]

One way to compile against a specific version of a library is to play with 
the .so links, as I believe these are what ld uses when doing dynamic linking.

Something like

rm /usr/lib/libc.so
ln -s /lib/libglibc-2.2.5.so /usr/lib/libc.so

You may also have to play with /usr/lib/libm.so just to try to keep the 
dependancies for glibc-2.3 out of the picture.

For the most part the only thing I seem to recall .so files being used for 
was for ld (and of course explicit calls using dlopen()).  I think doing this 
rpm *may* use the correct dependancies.
