It’s located in the same directory as the pluginfile and I was stupid 🙂
Running with the full path to the file works great, however that’s just for testing. I also had allow_url_include=Off which led to the initial errors. This is how it looks now:

function wp_compressor_header() {
require_once('http://www.bastelbude.com/wp-content/plugins/wp_compressor/class.compressor.php');
$compressor = new compressor('css,javascript,page');
}

however, I get an error that tells me the class “compressor” can’t be found. This is what the head of the class in the second php file looks like:

class compressor {

/**
* Constructor
* Sets the options and defines the gzip headers
**/
function compressor($options=null) {
[...]

and I get:
Fatal error: Class 'compressor' not found in [...]/wp_compressor.php on line 56
which is:
$compressor = new compressor('css,javascript,page');
