[bug-gettext] The 'sed' program is not GNU sed. Try installing GNU sed.

[Jeffrey Walton]

Hi Everyone,

I am trying to build and install Sed on OS X. To build Sed I need to
build and install iConvert and Gettext first.

There seems to be a dependency issue when building Gettext for Sed:

../build-aux/moopp  ./fd-ostream.oo.c ./fd-ostream.oo.h ./ostream.oo.h
../build-aux/moopp  ./file-ostream.oo.c ./file-ostream.oo.h ./ostream.oo.h
moopp: *** The 'sed' program is not GNU sed. Try installing GNU sed.
moopp: *** Stop.
moopp: *** The 'sed' program is not GNU sed. Try installing GNU sed.
moopp: *** Stop.

Any ideas how we can work around the issue?
