Comment (by ballapete):

 I built from source today. I do not remember which version was installed
 before. It failed too, so I upgraded all, also the Xcode command line
 tools, and then built `gv` again, assumimg the binary package could be
 faulty.

 Upgrading `gv` from the binary package makes it work. Thank you!
