There's a fix, very probable for version 2.8:

"Make pigz compatible with two-component zlib version numbers.
  madler committed Aug 18, 2023 "

I checked the zlib_vernum() by compiling it in a separate main,
and it does the right thing.

So probably upgrading pigz to 2.8 is the right thing for OI, too
(it's currently at 2.7, but I can't find the source for it).
