The PC file seems to be the culprit: Mine has bzip2 among the required private libraries but not among their switches… Recreating/Reinstalling the libbz2 PC file seems to work: pkg-config does not return an error. (Ghostscript has to wait until other build have finished.)

[ballapete (Peter "Pete" Dyballa)]

Replying to ballapete: Rresetting the PC file your contents allowed Ghostscript to build!

[kencu (Ken)]

Can we sort out why your freetype pkgconfig file came out like it did? I'm not sure how it came to pass that your pkgconfig file for freetype was different than mine...

[kencu (Ken)]

copying you in Ryan as freetype maintainer, as it --appears-- that is where the issue is here?

[ballapete (Peter "Pete" Dyballa)]

Replying to kencu:

Can we sort out why your freetype pkgconfig file came out like it did? I'm not sure how it came to pass that your pkgconfig file for freetype was different than mine...

The reason is clear: I saw that configure failed to determine that bzip2 existed by means of a PC file, not seeing that it detected its existence by other means. So I created the PC file (#61365). When I discovered that it's not necessary I removed it – not taking into account that Freetype now was referring to this non-existent file and passing this to its consumers. I saw this finally when I invoked pkg-config with --debug.

Sorry for this nonsense!
