Okay. Sorry. I thought that they would have had the same dlopen
issues.

HAVE_LIBDL is a misnomer, and should perhaps be renamed to
HAVE_DLOPEN, since the additon of a library that contains dlopen is
handled separately.
Does libtool's configury detect that there is a dlopen function on
NetBSD, but forget to set HAVE_LIBDL? I just backported AC_LTDL_DLLIB
to branch-1-4, so cvs updating may be fruitful...
Thanks for persevering with me :-)
Cheers,
Gary.
