*Update to version 2013.1.13 of NTFS-3G
Changelog can be found here: http://www.tuxera.com/community/release-history/ *fixed bug where deleting a file / directory returned always success (0) *change make install to default to wii-install and seperated cube-install *wii-install copies files to $PORTLIBS path now
