devel/GConf fails to build on -current "#~| msgid"

[David Brownlee <abs%absd.org@localhost>]

Just updated pkgsrc on my amd64 boxes and the netbsd-5 box builds
devel/GConf fine, but the 5.99.49 box (using identical config) fails
to build with

es.po:2725:4: parse error
es.po:2725: missing `msgstr' section

The offending line is the first of the block:

#~| msgid "Could not send message to gconf daemon: %s"
#~ msgid "Could not send message to GConf daemon: %s"
#~ msgstr "No se pudo enviar un mensaje al demonio de GConf: %s"

commenting out the block on that and three other .po files allows the
build to complete.

Both netbsd-5 and 5.99.49 boxes report a msgfmt of 0.14.4.

Has anyone else seen this - anything I'm missing?

thanks
