Looks like if I build for unstable, I'll pick up a Depends on libneon27-gnutls (>= 0.29.5) which isn't in testing. Should I target TPU instead?Unfortunately t-p-u isn't an option in this case, as the package has the same version in testing and unstable (dak requires that t-p-u uploads satisfy testing < t-p-u < unstable).
Would a sensible approach be to upload the package to unstable? then if dependencies turn out to be a problem make another upload as appropriate.
That way the changes get tested in unstable sooner rather than later and if a TPU upload is needed it becomes possible.
