Build tips (MacOS)

ToDo : http://support.web-education.net/issues/25311

On MacOS, the sed command does not works as the Unix' one. In order to make the build system working well, you can use the Brew package gnu-sed.

brew install gnu-sed

This installs a new gsed command that behaves like the Unix' one. As mentioned by the command-line, you may want to make the sed command point to the gsed instead of the Darwin(MacOS) version. Put the the command that is printed on screen in your ~/.bash_profile, which be like :

PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"
source ~/.bash_profile```

Now you `sed` command point to the `gsed` installed by this package.
