A follow-up to my own post. I managed to get ardour-2.9999 to build with
some changes to the ebuild, see the diff below.
(ESVN_RESTRICT is used to prevent the svn export from happening,
subversion_wc_info is called to update ESVN_WC_PATH)

I am rather new to writing ebuilds, can anyone check whether I didn't
use non-allowed practices?

Thanks,

Matthijs
