I can fix this only by updating php?

You should be able to upgrade PHP to fix this. However, try composer install --no-dev -o
That should skip phpunit, which isn't required to run Polr.

If you're on 5.5.9, you might want to hold off a bit or upgrade your PHP version, though. There is currently an open bug that affects version 5.5.9 that needs to be fixed. #264

You can revert to a previous commit with git checkout

@urbels I've released a patch for 2.1.0 in 2.1.1 to solve the class constant error. If you upgrade to 2.1.1 and run composer install --no-dev -o, you should be good to go :)
