Comment (by ryandesign):

 Okay. I didn't think about updates to ocaml breaking other ports, but now
 that you mention it I do recall that in the past.

 What motivated my filing this ticket was [ticket:59399 a lablgtk2 build
 failure report]. Both lablgtk2 and ocaml are outdated, so I figured a good
 first step would be to try updating one or both of the ports to the latest
 version.
