I have posted patches for ALSA-utils/lib 1.0.16 (see bug 4014) these look
like above.  What is the --with-versioned=no option.  I have not used it but
it all works for me with 1.0.16. 
Maybe you could take a look at the patches on 4014 and update if necessary.
That way we can close BUG ticket and update ALSA both of which are good :-)

Cheers
Dan
