 I also tried on macOS Catalina, where I do not see this 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`.

 In the case of grads I'm not sure whether the use of `strip` is involved.
 I see in my grads build log:
 {{{
 checking for strip... strip
 }}}
 {{{
 checking whether stripping libraries is possible... yes
 }}}
 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.

 But I do see this same black window on macOS Catalina (with or without `-h
 GD`). Maybe that's what it's supposed to do; I don't know this software.
