The problem is things like i386-wine are providing libxml2 as well which SO= NAME is also libxml2.so.2 how do we differentiate both ? To be honnest I have an idea on that but that requires modifications on the ports tree side as well as pkg so it will have to wait a bit. regards, Bapt --KRJ4yArSHF8vY7I3 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlPjtnMACgkQ8kTtMUmk6EwjDwCbB6FPfKdcb9ixn+qy8Tf1zlLj u6MAoLBUc1tj+I3wZLwX6hJx/MKUGlP2 =bY3O -----END PGP SIGNATURE----- --KRJ4yArSHF8vY7I3--
