Isn't your email/request rather a pretty good example why installing
software to /usr/local is a bad idea wrt to system upgrades?

I'd really suggest to install your special libraries, local software
etc. either to /usr/local/$PACKAGE or /srv/local/$PACKAGE or somewhere
else. You can use environment variables or rpath to make them work.
