There has been no new official release of age,
but some important fixes and changes have been
done since the last release in December:
FiloSottile/age@v1.0.0-beta2...f0f8092

patchelf seems to generate an ELF that "strip" cannot process:

  strip: /tmp/stNGAZvd: not enough room for program headers, try linking with -N
  strip:/tmp/stNGAZvd[.interp]: bad value

(This unfortunately does not cause any errors or even error output in
the build log, since the default strip hook redirects them to /dev/null
and ignores failures.)

The lack of stripping ends up leaking paths to the compiler in the debug
symbols. This more than doubles the transitive closure size of
alacritty.

Impact on closure size: 314.5M -> 131.8M.

This is the legacy version for OCaml ≤ 4.02

ocamlPackages.bistro: fix for core-0.13
ocamlPackages.phylogenetics: 2020-01-05 → 2020-01-25

Only the actual shared libraries are required to be installed, and they
are imported directly by path via ctypes. The package's patchPhase
already takes care of embedding the Nix store paths of the required
libraries into pyopengl.

This reduces the transitive closure size of PyOpenGL: 622M -> 136M.
