Well, the problem on Mac OS X was that the library I was compiling  
with (mp3lame) was not installed in
a standard location, so the lrintf detection in configure was failing  
(because the lib was not found during linking).
I have sent a patch to actually use CFLAGS/LDFLAGS to fix the issue,  
but it means that if you are using
some libraries which are not installed in a standard location, you  
need to add the appropriate --extra-ldflags
and --extra-cflags to specify some additional paths for libs/includes.

I guess a better way to fix it would be to avoid linking with extra  
libs if not required for the lrintf detection.
I hope this helps.
