I have now got errors on all my machines everywhere with:

checking for msgpack-c... no
checking for msgpack... no
configure: error: Package requirements (msgpack) were not met:

Package 'msgpack', required by 'virtual:world', not found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables MSGPACK_CFLAGS
and MSGPACK_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
make[1]: *** [Makefile:4065: configure-binutils] Error 1
make[1]: Leaving directory '/export/users/haochenj/env/build_master'
make: *** [Makefile:1033: all] Error 2

Should I re-install something? Should it be considered as a breaking
change that needed to be mentioned somewhere?

Thx,
Haochen
