 Replying to [comment:2 mascguy]:
 > Ryan, I'll have to do some digging during my lunch break. But perhaps
 one of the GIMP dependencies - and/or GIMP itself - may have required the
 latest Cairo release. (Despite 1.17.x being considered less-than-stable.)

 Longer-term, we may need to support multiple versions of foundational
 ports like `cairo`, `pango`, `glib2`, etc - via the same segregation
 scheme used for Boost and OpenSSL - as being locked into one version
 causes serious dependency hell. That's something I'd take care of
 maintaining though, so that you don't have to deal with it.

 I'm hoping to avoid that as much as possible, so don't get too nervous
 just yet. (And we'll certainly give you an opportunity to chime in, and
 provide feedback, before going crazy with more versioned ports.) But just
 a proactive heads-up, for future thought/consideration.
