That is unfortunate… It seems like zlib 1.2.12 was intentionally
unpublished, probably because of CVE-2022-37434, which was fixed in zlib
1.2.13. I also cannot find any mirror still serving the old version… but
you should be able to use 1.2.13 instead.

You can try installing ptxdist-2022.10.0, which includes the newer zlib
version, and update via `ptxdist-2022.10.0 migrate`. Until DistroKit is
updated to the new PTXDist version, you can try overwriting the zlib
version locally by putting the following text into rules/post/zlib.make
in your DistroKit tree:

    ZLIB_VERSION    := 1.2.13
    ZLIB_MD5        := 7d9fc1d78ae2fa3e84fe98b77d006c63
    ZLIB            := zlib-$(ZLIB_VERSION)
    ZLIB_URL        := http://zlib.net/$(ZLIB).$(ZLIB_SUFFIX) $(call ptx/mirror, SF, libpng/$(ZLIB).$(ZLIB_SUFFIX))
    ZLIB_DIR        := $(BUILDDIR)/$(ZLIB)

After that, `ptxdist print ZLIB` should output "zlib-1.2.13".
