You are correct on both counts:
- xz is needed to unpack the file - the comment in the script is correct.
  I incorrectly remembered that when I made the commit.
- After the gz file was gone, I noticed the new xz file and never checked for
  other formats.

Configuring, building and installing takes ~45 seconds on my system. Add to this
a 1 MB download. So if there are no objections, I'll leave it as is (and check
whether other packages also come in .xz format). Otherwise I'll change the stuff
to bzip2.

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
