Social login plugin trouble

Hi all,

I've begun to take a look at this plugin and eclipse complains of errors:
Parser error "')' expected in function call (trim)."    LightOpenID.php    /elgg/mod/elgg_social_login/vendors/hybridauth/Hybrid/thirdparty/OpenID    line 65   

Parser error "'}' expected in compound-statement."    LightOpenID.php    /elgg/mod/elgg_social_login/vendors/hybridauth/Hybrid/thirdparty/OpenID    line 77   

They seem related but being a complete newbie I can't ascertain if they are real errors or a glitch of Eclipse's php editor. Any hints about how can I solve it?

Any help appreciated!
