I don't understand what you're getting at, but I think you're 
complicating the subject unnecessarily.

Virtual packages are a well-established method of package creation in 
the various distributions and if done correctly, it works without problems.

For example, just have a look at the implementation for 
gambas3-gb-compress in PKGBUILD and gambas3.spec, that should be clear 
(it's not rocket science either).
