What I'm doing at the moment with Percona is exactly that. I change the 
Makefiles and patch the code to produce binaries and libraries that are 
completely different. 

And what I will do is create a simple RPM package that when installed will 
replace the MySQL package configuration and init script, and this way 
effectively giving the user easy way to replace the mysql packages installed on 
the machine.
