Yes, I had that already. In the previous package I had to add individual
patches, but now I can just point to a commit:

https://github.com/aconchillo/homebrew-guile/blob/master/Formula/guile-cairo.rb#L4

However, guile-cairo was not working because I was using guile from commit
(d8df317bafcdd9fcfebb636433c4871f2fab28b2) and that's causing a segfault
during scm_init_cairo (when defining all the procedures).

Anyways, guile-cairo is fine going back to stable 3.0.9.

The issue seems to be here:

(define-vfunc (snapshot-vfunc (self <drawing-widget>) snapshot)
  #t)

I just removed the whole body and replaced it for #t, just to test. All the
other ones that are failing also have a define-vfunc.

I haven't investigated what that is so I can't tell much more.
