Why? you can check for the existance of the (simple) variable Vorbis-Tools$Dir or use
IfThere <Vorbis-Tools$Dir>.vorbiscomment Then Else Error OggTag requires the Vorbis-Tools
That would show that that directory has been booted, and that vorbiscomment exists.
BTW, checking for the existance of the alias, is still no guarantee that it is set up to work correctly, just that it exists, so no improvement really.

I appreciate your enthusiasm for tackling the obey language though.
