It is not appropriate to compare MSI to the autotools. Apples and
oranges. The autotools are build tools; MSI is a means for
distributing and deploying binaries. It would be more accurate to
compare RPM to MSI.
RPM addresses "DLL hell" with inter-package dependency tracking. It is
not as end-user-friendly as MSI, but it probably does a better job of
ensuring the integrity of the system. I must admit, though, that I
don't know a whole lot about MSI.

"Nearly anything" won't necessarily accomplish what m4 accomplishes.

The "our consumers are developers" excuse is frequently produced as
grounds for shirking the issues of deployment. It doesn't wash; it's
not even true. Your consumers are the persons who need to use the
software you produce. Period. Ultimately, *somebody* has to deal with
deployment issues. You can pass the buck to other developers, but
don't have any illusions about doing so. When the buck is passed like
this, it means a bunch of people downstream have to solve the same
problem individually because it wasn't solved at the source. The
upshot is that the barrier to using your software is raised.

Installation must be as simple as "./configure;make;make install". It
doesn't have to be those commands exactly, but that spirit of
simplicity must be intact. If Boost can get there with Jam, that's
fine by me.
