Sorry, no can do, but I can definitely test your patch.

Yup. This is how I diagnosed the problem some time ago. Not linking the
DSO library makes perfect sense on all platforms.

You know...that's already fixed... Guess what? all you have to do is

    --enable-all-static --disable-dso

When the APR configure sees --disable-dso, it does (surprise, surprise!)
exactly what you want.

The big gotcha is that it still doesn't work. Instead of not finding the
dynamic linker library, which it doesn't look for any more, it's not
finding the symbols themselves (shl_load and friends on HP-UX). Those
references are coming from libnsl.a, which is a system library. So I
think we're screwed with an all-static build on HP-UX.
