prawn-gmagick is a Prawn extension that uses GraphicsMagick to embed image
formats Prawn's built-in code does not understand (notably WebP). The gem
ships a C extension that links against libGraphicsMagick via pkg-config, so
graphicsmagick and pkg-config must be in scope at build time.
this creates some eval errors that will be fixed in the next commit
done with the following script:
```fish

While this reverts regressions, this has to cause "new" regressions.
The problem here is that the previous regressions are relatively recent,
still, and the previous regressions are ***much worse*** than the slight
newer regressions that fixes the older regressions.
Note that this is not regressing the packages that are "newly"
regressing prior to the versions they were beforehand. They are now
currently pinned in a pessimistic manner, to correctly fix the problems
in the way that was initially intended.
