No - they /are/ needed. Lets say my package wants to compile with vorbis. 
I can't just add -lvorbis (what if its not installed!) - With this method 
you can just check for the library though.

But what if I want to check if the headers (found in -devel) are 
installed (say I have a #include <vorbis/vorbisfile.h>) with vorbis, I 
can figure out the include directory to pass to gcc. Otherwise I will 
never really know where the header files are (and note: if -devel isn't 
installed you can't compile (if you use the header files).

So I still maintain they are needed for people who wish to write 
applications based on libvorbis/libogg (mainly for checking that header 
files are installed, checking for the version of ogg/vorbis, and figuring 
out the correct flags for linking with ogg/vorbis 
(-I${vorbisprefix}/include -L{vorbisprefix}/lib etc.)
