>Description:
inputmethod/ibus-mozc build *sometimes* fails due to lack of
some dependency information (probably in upstream sources).

"MAKE_JOBS_SAFE= no" was added recently in ibus-mozc/Makefile rev 1.24
 http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/inputmethod/ibus-mozc/Makefile#rev1.24
but it doesn't help at all in this case.
(because ninja ignores it or ${_MAKE_JOBS} is explicitly passed?)

>How-To-Repeat:
(cd pkgsrc/inputmethod/ibus-mozc && make clean && make package)

it sometimes fails like:

Note /etc/mk.conf has MAKE_JOBS=8 in this case and
the build machine has 8 logical cpus (Core i7-3770),
so I guess "ninja -j 16" is chosen by ninja/gyp.

>Fix:
It seems to work around to build ibus_mozc_lib separately.
