libcurl is part of the curl package. It's used by ogg123 to handle streaming, 
and it was necessary to have a recent version installed to build ogg123 last
time I built it from source (I believe this has been acknowledged as a build 
bug, as streaming isn't necessary for most of what ogg123 does). 

libasound is the ALSA driver library interface, but I'm not sure whether it's 
for the pre0.5 or post0.5 version of ALSA - which is important, because the 
API is quite different between the two, and I think libao can be built for 
one or the other, but not both.

Strictly speaking, you shouldn't _need_ those libraries, so you could force 
the installation.

Weird. It might be part of the streaming code. Again, you'll probably be 
fine forcing the install.

Hacking libao and the vorbis tools to fail gracefully when you try to use 
capabilities that it's built for but lacks library support for would be good 
(if it hasn't already been done). Then the optional libraries like libasound 
could be drop from the dependency list entirely.
