Just to keep the list up to date, and recap what has been found:
The following Makefile.PL produces a 0 byte Makefile under MP2.0.2,
OpenBSD 3.8-RELEASE, perl 5.8.6:

On a whim that it might be a double loading of APR issue between
Makefile.PL, and EU::MM eval-ing my Handel.pm, I changed the Makefile.PL
to this:
> use ExtUtils::MakeMaker;
> use APR;
> my $r = WriteMakefile(
> NAME => 'Handel',
> VERSION => '0.28',
> AUTHOR => 'Christopher H. Laco',

That still creates a 0 byte Makefile.
Adding a print statement to this makes it work:
> use ExtUtils::MakeMaker;
> use APR;
> print 'foo';
> my $r = WriteMakefile(
> NAME => 'Handel',

Just to reinforce that notion, if I add this to APR.pm:
> BEGIN {warn 'using custom APR'};
I get the full Makefile.
Commenting out:
> sub dl_load_flags { DL_GLOBAL }
or it's use constant DL_GLOBAL has an effect on the problem.
No incantations of use/require, eval{}. eval '' solve the problem.
I've also noted that I have massive SQlite test failures on this box
with things like:
> DBD::SQLite::db do failed: database is full(1) at dbdimp.c
> DBD::SQLite::db do failed: database schema has changed(1)
> DBD::SQLite::db do failed: no such table:
that immediately went away when I removed use APR from my main module.
...only on OpenBSD.
At this point, the level of magic required to further identify and fix
this issue is way above my skill level. Unless anyone has any further
ideas, it looks like I need to refrain from using APR [outside of
Apache/MP] in this platform.
My real concern is what else XS/IO related is borked in this kind of
scnerio...
