Yes, although I wasn't actually able to pull this off when I tried it:
`port extract && port uninstall xz && port build` reinstalled xz before
attempting the build.

> Are you saying emacs actually uses unlzma during the build phase? I can't find evidence of that by grepping the source. I'm assuming it's only used to extract the tarball, and that when the port was added in r77907, J?r?me did not realize that the depends_extract keyword existed, nor that "use_xz yes" would automatically add the needed unlzma dependency to depends_extract for you. This revision corrects that.

Right.
