  76         # WARNING: Please read on bumping or applying patches!
  77         #
  78         # There are two circular dependencies to be aware of:
  79         # 1)
  80         #       if we're bootstrapping configure and makefiles:
  81         #               libxcrypt -> automake -> perl -> libxcrypt
  82         #
  83         #   mitigation:
  84         #               toolchain@ manually runs `make dist` after running autoconf + `./configure`
  85         #               and the ebuild uses that.
  86         #               (Don't include the pre-generated Perl artefacts.)
  87         #
  88         #       solution for future:
  89         #               Upstream are working on producing `make dist` tarballs.
  90         #               https://github.com/besser82/libxcrypt/issues/134#issuecomment-871833573
  91         #
  92         # 2)
  93         #       configure *unconditionally* needs Perl at build time to generate
  94         #       a list of enabled algorithms based on the set passed to `configure`:
  95         #               libxcrypt -> perl -> libxcrypt
  96         #
  97         #       mitigation:
  98         #               None at the moment.
  99         #
 100         #       solution for future:
 101         #               Not possible right now. Upstream intend on depending on Perl for further
 102         #               configuration options.
