I'll give it a whirl soon. Thanks for working on this! All the changes sound really positive!

Still looking for more feedback, but I'm actually starting to like the multiple method approach, and I've restructured a lot of the Makefile.am's to make the implementation clean.
Derek, this should address the cd hassle for you. Of course subdirectory builds still work, and I really like these to segregate builds by compiler or machine - while still sharing the same source tree - but it is no longer required to get multiple methods.
Also, --disable-examples is implemented and does what you'd expect - perhaps most importantly speeding up make install.
Finally, I got frustrated that reconfigure forced a major rebuild. This was because we were textually time-stamping the autoconf-generated headers with the time at which configure was invoked. This information is not that useful, and triggered a lot of unnecessary rebuilds, so I got rid of it. Of course, libmesh_here() etc… still has access to the *compiled* date, which is arguably more relevant anyway. Importantly, though,
$ ./configure …
$ make …
$ ./configure ..
$ make # is now a no-op!
So, as usual, I created a "feature" branch and turned it into a "kitchen sink update" branch. Sorry about that - its hard to be disciplined and only change one thing at a time…
To summarize - I think this is a good move, if consensus is it is in the direction of good I'll merge and then start updating the installation instructions on the web page. So please check this out.
