Of course not.  mod_ssl's legacy goes to apache's legacy of breaking
compatibility early and often when it made things better/easier/simpler.

Apache 2.0 and APR 0.9 (soon 1.0) have avoided that approach as best
as possible (the poll API being the big exception.)

If you need apache 2.0 you need apr 0.9.  The API should be stable.

If you need apache 2.2 you will need apr 1.0 (or 1.1 if changes happen
to make 2.2 a possibility).

And within a given point release, apache 2.2 or apr 1.1, nothing will 
be broken.  That's the contract we are aiming for to avoid the very 
headache you describe above.
