getting started ...

will need virtualev
  easy_install virtualenv

now setup our sandbox 
... where ever you want it located
... whatever you want it called, here i named it djangodev
... no-site-packages config is up to your setup
... step into new development environment
  
  virtualenv --no-site-packages djangodev
  cd djangodev

once cloned, setup new env, clone git repo into you virtualenv as limestone (app sandbox directory)
... step into your_new_app dir
... and bootstrap structure, this will install needed files and directories
  git clone git://github.com/bhalle/limestone.git
  cd limestone
  python bootstrap.py

then once django app struct is created 
... run buildout to download all dependencies (see buildout.cfg for details)

  bin/buildout

that should be it, since the migrations (south) are included in code just make sure db config is correct
... syncdb for default admin
... populate database tables
... start dev server
  bin/django syncdb
  bin/django migrate
  bin/django runserver

note: if your having problems with mysql ... make sure you have it in your path
