Hmmm, after thinking a little more I find that the current solution
is not so bad. What is needed is a good behaviour at compile time
and then /dev/sndstat might not be present. The important thing
is to check whether libasound.so exists and to avoid any references
to its entry points if it is not present. The amount of needless
code for ALSA that would be generated on a system with OSS which
has a libasound.so file is insignificant. I was just careless not
testing what happens when the file is not present... 

I have corrected the setup bugs and replaced the Linux package
with linrad-02.45a here:
