Wrong error message with MySQL 5.6

[Martin Arrieta]

When you are trying to make a backup from a MySQL 5.6, you are displaying the following error:

shell> innobackupex --defaults-file=my.sandbox.cnf backup/

This error is when innobackupex is trying to guess or execute the xtrabackup_?? binary.

In that case, the xtrabackup or in this case innobackupex should return something like "MySQL 5.6 is not supported yet"

Thanks!
