That example makes no sense. they have the proper runtime to get things
working. in that sense, you should have libraries at the runtime which contains
mkostemp.

See what linux distributions does. they usually have packages per releases, in
some cases except when ABI/API isn't changed.

also mkostemp is preferrable more than mkstemp for security reason. I don't
know how macports works though, if providing binaries per releases is
difficult, you could maintain that patch there.

Anyway, according to what you said, it worked when they had mkostempin the
library. they broke the compatibility. then you know something which requires
missing pieces will also miss the compatibility unless rebuilding. that is my
position on this.
