Lets not forget that simply using any given build system doesn't magically solve all the issues. If a `make install` invocation gzips manpages instead of the package manager or distro hooks, then you won't have reproducible manpages unless the upstream uses the `-n` switch as well. This is just an example of many small and obscure issues that hide inn different upstream projects.
