$ perror 1
OS error code   1:  Operation not permitted

Check permissions on the directories and files... the data dir and its
contents should be owned by user 'mysql'.

Something like this should fix you up:
chown -R mysql:wheel /usr/local/mysql/data

Also make sure that you're copying *all* the files; MediaWiki prefers to
live in InnoDB tables, which by default carry most of their data in the
big ibdata* files, not in the tiny table description files in the
individual subdirectories.
