PayPal SOAP: "Declaration of PayPal::raiseError() should be compatible with that of PEAR::raiseError()"

I have downloaded the Paypal API for PHP (SOAP) and I'm getting this error:

Strict standards: Declaration of PayPal::raiseError() should be compatible with that of PEAR::raiseError() in ....paypal/PayPal.php on line 24

when I call this:

$handler =& ProfileHandler_Array::getInstance(
        array(    'username'        => $this->api_username,
                'certificateFile' => $this->api_certificate,
                'signature'       => $this->api_signature,
                'subject'         => $this->api_subject,
                'environment'     => (($this->api_test)?'Sandbox'开发者_Go百科:'Live')
        )
        );

Any idea?

Javi
