I just changed the guile-cairo entry in pkgsrc to guile 2.0 (we are
belatedly switching).

It is at 1.4,1, the last actual release.  I see on savannah:

  http://www.nongnu.org/guile-cairo/

that there is a 1.9.91 preelease, but no actual following release.

Is there a release later than 1.4.1?

It seems guile-cairo is required for guile-gnome.  Is that really true?
What are others doing?
