Please, let us have a look, too: at your configure line, at all
  libtool --mode=link
lines and their output.

The issue of dependent DLLs having to exist in $PATH is exactly this bug:

That is what -dlpreopen is documented to do.  -dlopen should use the
static versions only when shared libs are not available, e.g., due to
--disable-shared or some other reason.
