That's true.  But my question was actually specific to when the
systems are sharing basically the same environment (kernel, library
versions, etc.).  A simple solution is that on each system I install
qemu official package then the dependencies will all be there, then I
install my custom package (which will possibly install the binaries
under /usr/local) and I run the customized binary.

I would prefer avoid using git and compiling stuff, if there is a
way. :)
