My script for Arch seems to work:

https://aur.archlinux.org/packages/zi/zita-convolver/PKGBUILD
It effectively only does: ln -s libzita-convolver.so.3.0.2 /usr/lib/libzitaconvolver.so

so it just creates a symlink to the versioned .so
Apps expecting the old lib will simply fail.

Not sure how to do it from the makefile or in some other package

management system.
