Pick up httpd 2.0.63 and the current apr versions!  You need to understand
that 0.9.4 -> 0.9.13 (which is already years too old!!!) was a larger
jump than binary compatibility will permit, and that you broke binary
compatibility again when you let APR pick up the presence of IPv6, which
might or might not have been present when the 0.9.4 was first installed.

0.9 doesn't exactly respect the same binary compatibility rules as versions
1.0 and later, because the rules were still evolving rapidly.  When finally
the httpd 2.2 shipped, using apr 1.x, things had settled in and both the
projects are better able to enforce binary compatibility.

With your old and new APR libraries, you just swapped in a BMW engine
underneath the hood of your VW beetle, and this probably isn't the only
side effect of a badly fit component.
