Great.  Once you finished the build I will give you a template of dm2
from git recipe.  Just fill in the git URI.

For dm2 you don't need that long.  I have this setting in my
local.conf (the one under moko/build/conf once you finished `make setup')
and it's a big time saver.

GLIBC_GENERATE_LOCALES = "en_US.UTF-8"

OE downloads everything and builds the toolchain by itself so the
first time will be slow.  It will be easier after that.

It's basically the same thing on the mokomakefile wiki page.  Maybe we
can enhance that page.

Check ~/moko/build/packages/openmoko/openmoko-dm2_svn.bb
(or https://svn.internal.openmoko.org/trunk/OE-overlay/packages/openmoko/openmoko-dm2_svn.bb)
You will see
SRC_URI = "svn://svn.internal.openmoko.org/trunk/production_testing;module=dm2;proto=https"

It actually means

https://svn.internal.openmoko.org/trunk/production_testing/dm2
