Comment (by korria):

 Replying to [comment:4 ryandesign]:
 The black window is normal. The software plots output from weather models.
 It works fine on x86_64, just not on my arm64.  I wonder if it is a gcc
 problem?

 > This is reminding me of #64448. In that case, "symbol not found in flat
 namespace" was happening when running cscope only on macOS Monterey, and
 only because the Portfile was running `strip` on the cscope executable
 after it was built. We fixed the problem by no longer running `strip`.

 involved. I see in my grads build log:

 > however I don't see whether any stripping is actually happening. (This
 may just be something all configure scripts check for.) If you can
 determine if stripping is happening, and if you can prevent it, maybe that
 will have an effect on this problem.

 `-h GD`). Maybe that's what it's supposed to do; I don't know this
 software.
