Agreed.

Personally I would compile all of the dependencies so as to ensure a
consistent ABI.

My preference order is the opposite.

I prefer +DD64 over +DA2.0W because +DD64 works on both ia64 or parisc
and therefore the same build script/makefile can be used on either.
In the grand scheme of things +DD64 is newer than +DA2.0W and was
created just for the reason of cross hp platform consistency.

If you can avoid needing anything but the client binaries then I would
avoid building apache and the associated modules and just build that
clients only. It is a huge simplification and then things just work.
