Because people didn't pay any attention to the fact that configure's 
"--help" output explicitly said that "--disable-frontend" and 
"--disable-backend" were for porting /only/ and would break your build 
on Linux systems, and because all my yelling


failed to convince people that the options were not for their use (and 
that they didn't want them, anyway), the devs (finally) modified 
configure to ignore those options. The following lines are taken 
directly from configure:

# disabled due to abuse in Gentoo ebuild
# --disable-frontend) frontend="no"
# ;;
# disabled due to abuse in Gentoo ebuild
# --disable-backend) backend="no"
# ;;

(The reason Gentoo is singled out is because users of other 
distributions are more commonly using packages compiled by a package 
manager who knows what he's doing. However, as long as the ebuild still 
contains the "frontendonly" and "backendonly" USE flags, the ebuild is 
still abusing the options--granted, Myth ignores the abuse, now, but 
it's still abuse.)

Oh, and in case you're thinking of doing something with it, let me 
proactively say you don't want to use "--disable-audio-oss" either.
