If you did not build wxWidgets from source, you can try doing that and see if it fixes the problem. Let us know whether or not that fixed it. If 12.4 didn't fix the bug, then a workaround is given in the mailing list thread linked in that ticket.

I am just a MacPorts user, not a maintainer or anything, but I can tell you what I recently learned about building from source.  I also looked in the Guide and found nothing, but "man ports" mentioned source mode (among many, many, many other things).

Here is something to be aware of, though.  If you simply do

  port -s install whatever

then MacPorts wants to build all the prerequisites from source too, unless it happens to be installed already.  This is usually not what you want, because some of those prerequisites take a long time to build, and really, why do that instead of just the binary install for those?

What I eventually figured out was that I could first tell MacPorts to install the prerequisites, explicitly, and then after that do the source install of just what I am after.   The incantation I used for the former was

  port install depot:whatever

(Put sudo before the installs, of course.)

Hope this helps.
