I recently acquired a Gumstix overo board and wanted to get the build environment set up on an Ubuntu Linux desktop.  The instructions I found on the gumstix.net website for setting up the build environment consist of several steps that require an Internet connection for checking out code from an svn repository, downloading various packages, etc.  Is there a fairly straightforward method to get this set up offline?  The desktop I'm using cannot be connected to the Internet.
