sigh... yawn... well, I don't care either way.  But it may be a little
presumptuous to do it in a non-threaded perl....

Make sure to add this to devel/libltdl/{Makefile,} as well.
Everything using libltdl is using dlopen(), though not everything using
libtool necessarily is.  (Some packages still need to be fixed to use
devel/libltdl/ because they are using non-pkgsrc-fixed copies
of libltdl bundled in their source trees, but such packages are using dlopen
as well.)

As to how to do the PKGREVISION bump:  I'd recommend BUILDLINK_RECOMMENDED
for this purpose, per my suggestions on how to use RECOMMENDED most
effectively, so that folks who "know what they're doing" by setting
IGNORE_RECOMMENDED=yes are not forced to upgrade right away.

Note that this assumes the bump does not cause an ABI change for loadable
modules.  If the change is ABI-afflicting, then BUILDLINK_DEPENDS should be
bumped, as well as all direct descendants (non-recursively).
