In hopes of working around
https://github.com/NixOS/nixpkgs/issues/60845. This fetches a gz archive
instead of xz and also fetches the archive from a different source,
hopefully avoiding the issue (whatever ist is caused by).
In addition to that, I think that building directly from VCS is
generally cleaner and more flexible for the following reasons:
- It cuts out and unnecessary middle step.
- It makes sure the version users install is equal to the version users
may have vetted.
- It makes it easy to develop patches or bisect changes by simply
checking out a different rev.
- It avoids using upstream-provided "binary" artifacts like those
generated by autotools.
