This "suddenly" is since 8 months ago, to be specific, in
  http://trac.macports.org/changeset/98363.

The corresponding ticket [1] states that libiodbc fails to build against
gtk2 +quartz. The same ticket also mentions a possible solution:
Building libiodbc without a gui, i.e. with --disable-gui should avoid
the dependency on GTK.

If you're interested in getting this resolved, please test whether
libiodbc will build against gtk2 +quartz. Providing a patch that will
make building with --disable-gui the default and moving the GUI and the
GTK dependency to a variant also sounds like a good idea. Since libiodbc
does have a maintainer, feel free to open a ticket and Cc him.
