>Description:

We cannot build pkgsrc/devel/gmake due to circular dependency bug if
PREFER_PKGSRC=yes defined since gmake with NLS support (enabled by
default) depends textproc/expat via gettext-tools.  But textproc/expat
requies gmake. So gmake depends gmake. The build fails.

It looks this bug has been existed from 2014 fall to now.


>How-To-Repeat:

Set PREFER_PKGSRC=yes in /etc/mk.conf, build gmake:

# cd /usr/pkgsrc/devel/gmake
# make

>Fix:

unknown.

Its workaround follows:

1.	specify PKG_OPTIONS.gmake= -nls in /etc/mk.conf.

2.	PKG_OPTIONS.gmake= -nls in pkgsrc/devel/gmake/options.mk by default.

3.	modify gmake building to two stages: build gmake without NLS support once, and rebuild gmake with NLS again ?
