---------------------+----------------------
 I spent some time trying to upgrade **graphviz @2.50.0_0** to **graphviz
 @6.0.1_1** as per the normal route.

 However, I kept running into the same wall (see attached log if interest
 exist). I browsed through other tickets trying to find a potential
 solution. The closest I found was the closed #64323. It is not identical,
 but the effects were close enough that I started digging through the log
 with a different focus. I figured out that what seemed to trigger the
 failure was an:
 `Error: Unable to find 'go.swg'`

 So, I checked whether ''swig-go'' port was installed, and it wasn't. So
 after building that port I tried again upgrading ''graphviz'' and it
 worked as expected and the build finished without errors.

 So a simple solution for this would be to add ''swig-go'' as a dependency
 (I am unclear if this is applicable to all variants or just a subset).
