My composer.json lists these requires: "require": { "php": ">=5.5.9", "october/rain": "~1.0", "october/system": "~1.0", "october/backend": "~1.0", "october/cms": "~1.0", "laravel/framework": "5.1.*", "wikimedia/composer-merge-plugin": "dev-master", "laravel/homestead": "^3.0", "laravel/elixir": "^1.0@dev"

Doing the install: php artisan plugin:install RainLab.UserPlus yields this error:
[ErrorException] Division by zero

Since your plug-in Profile requires this plugin, perhaps you can fix it so that it will install without throwing an error?

Thank you,
