While waiting for GitHub sync to be fixed I manually pulled in a change 
similar to what wiz committed to my macOS branch, but there are still 
other issues:

  # bob status cmake
  PKGNAME                             STATUS               REASON
  cmake-4.4.0                         unresolved           Circular dependency: cmake-4.4.0 -> curl-8.21.0 -> openldap-client-2.6.13 -> groff-1.24.1 -> netpbm-11.02.09nb8 -> libjpeg-turbo-3.2.0nb2 -> cmake-4.4.0

Adam's groff update also included this line:

  +DEPENDS+=      netpbm>=10.0:../../graphics/netpbm

but again I don't know why this is now necessary (it feels pretty 
heavyweight to me, especially as groff is often a core tool).

I think we're going to have to do this.  I'll see if I can get some time 
to do it.  As for which version to select, I would pick 3.31 to ensure 
the broadest support, unless there are any objections.  I don't think we 
can go any earlier due to threads like this:
