The problem is, not too many tools are available at that point during the build

Do you have gdb? You could set a breakpoint on pp_seek and call sv_dump on the sv.

My speculation is that unpack in miniperl is setting SvIOK when it shouldn't be.

But IOK should be set for unpack L. Maybe it's some bad combo of IOK and pIOK.
