This module is a wrapper around the libogg and libvorbis libraries. These
libraries (along with their development tools - which are also required)
should be available as prebuilt packages for your Linux installation.
For example, if you're using Ubuntu, you can install them with the command:

  $ sudo apt-get install libinline-perl libogg-dev libvorbis-dev

Otherwise, you can get them from https://xiph.org/.

If your build fails with messages about missing libraries (or missing C
header files) then this is probably the reason). Please install the missing
libraries and try again.
