Yes, we've known this problem is brewing. The prevailing opinion is that
it should just be a mutually exclusive configure time option. The
situation is that bad unfortunately.

vg needs quite a bit of love at the moment. Fixing the boilerplate is the
first job. Then make sure the upload and download of images is correct.
After that it is removing enough code to start passing the test suite and
then gradually add it back, testing as you go.

As far as I know, nobody is currently working on the VG backend. It's been
on my wishlist -- especially to have a VG, GL and image backend for the
same hardware. Please do fix it up and you are welcome to as much help as
we can muster.

Try #freedesktop on irc.freenode.net,
sitewrangers at lists.freedesktop.org, or just file a bug.

I hope you can get the issues resolved and return to the usual happy state
of Cairo development.
