The current code is a bit of mess.

For one - I don't know why the GNUPackage requires URLs to be split up as such:
>>>>>
    self.downloadpath      = 'http://ftp.mcs.anl.gov/pub/fathom/'
    self.downloadname      = 'moab'
    self.downloadfilename  = 'moab'
    self.downloadversion   = 'nightly'
    self.downloadext       = 'tar.gz'
<<<<

But ignoring this we currently have stuff like the following - where
the urls are attempted in the sequence specified. If the first one
fails - try the next one:

>>>>>
    self.download   = ['https://elemental.googlecode.com/files/elemental-0.79-p1.tgz',
                       'http://ftp.mcs.anl.gov/pub/petsc/externalpackages/elemental-0.79-p1.tgz']
<<<<<<

with [potential support] for multiple protocols. - as retrieval.py lists:
[we also support urls of type file://path]

>>>
# Fix parsing for nonstandard schemes
urlparse.uses_netloc.extend(['bk', 'ssh', 'svn'])
<<<<

And currently this default can be overwriten by user with:
--download-package=url

In this context we should not have a separate stuff for git
[self.giturls/self.gitcommit]. It should be rolled into the above
common url notation.

[note: the current git code ignores user specified
--download-package=url - and just goes ahead and does the git stuff
specified in package.py]

Somehow we have to add in 'prereqisites' to the 'repo' type urls in
the above scheme.

And then perhaps retrieval.py can be asked to ignore repo-urls with
some option like '--url-git=no'

Also - the repo urls need better support wrt: 'getting updates &
rebuilding package'.  Current code for this is tarball centric [with
some bad behavior - like not detecting a changed url etc..]
