Are you using composer to install and load the dependencies?

[sfortop]

Sure. I'm used composer
Main error - incorrect dependency for gettext/robo
missed required section in composer.json of package

current incorrect

    "require": {
        "php": ">=5.4",
        "gettext/gettext": "4.*"
    },

e.g. correct

    "require": {
        "php": ">=5.4",
        "gettext/gettext": "4.*",
	"consolidation/robo": "1.0.5"
    },

Ah, ok. I was not sure if robo should be included as a dependency or not (this is a task for robo, it's supposed to have robo installed, and sometimes it's installed globally), but maybe you're right. I've updated composer.json file.
