For a library consisting entirely of new code any license complying with the $osd is likely to be acceptable, but the $mit, $gpl2 and $apache licenses may be the easiest to adopt. Include both contributor copyright grant clauses which are important for ensuring the integrity of the project's code base. The Apache2 and MIT licenses are seen as more permissive, in that it allows derivative works to include a separate license for new contributions.
