build from git

My version of Mulberry (4.0.7) is getting a bit crufty when running
on CentOS 6; I'm guessing it's related to version drift of underlying
libraries, etc.  Some features have stopped working, I get weird font
problems, etc. Therefore I figured it was time to try a from-source
build and see if I can get some problems resolved.

I'd prefer to build from the git fork.  Hopefully that topic isn't
verboten here :)

I did notice that after a git fetch of mbert/master and running
'autoconf' at the top level, that './configure --help' would fail 
out:

configure: error: cannot find sources
(Libraries/CICalendar/Source/CICalendarDurationValue.cpp) in . or ..

Those sources don't exist in the base git fork, so I'm wondering what
is expected there. Is the expectation to pull down those sources
via svn per <http://trac.mulberrymail.com/mulberry/wiki/opensource>,
or are there some git artifacts that are missing, or what?

If anyone has an outline of steps to bootstrap the build process
from the git sources, it would be appreciated.

(I'd search the mailling list archives on this, but it doesn't look 
like they're searchable and browsing the topics over quite a few
months hasn't caused me to find the details.)
