Thanks for the how-to!

On any system recent enough to have xz packaged, you should be able to
combine these steps as:

  tar xvf libogg-1.3.1.tar.xz

And if that doesn't actually work on CentOS, never mind. :-)

'curl -O $URL' is less error-prone. Or 'wget $URL' which downloads to
the basename by default. Not sure if CentOS includes wget in the base
system, but it's more common on linux systems than macs.

http://downloads.xiph.org/releases/opus/opus-tools-0.1.8.tar.gz is the
current release.
