Hmm.  You could, at the cost of code complexity, simply have different
driver loading mechanisms for various platforms.  Systems where you know
dlopen() works as you need, just use it directly, and on other systems
use libltdl.  I don't mean to say that's an ideal solution, but it is a
solution, if the .la evilness if indeed a true problem.

I had comments about that in my other mail.
