That's possible in principle, but not very practical.

Suppose the library L uses X and Y, with Y using X. You have X and Y 
installed as binary packages in /usr/include and /usr/lib.

But the library requires a newer version of X than what you've installed. So 
you fetch the source of X as well and build it. Now L builds, but Y is built 
against the preinstalled older X, whereas L is built against the newer X. 
ODR violation.

We could... in theory... put every revision of every library into

inline namespace d875a68ceb10081e30529e65ddef47297844e9f8 {

but... well.
