Issue with plugins directory.

MySQL community 5.6.17 uses the following directory for plugins, after I extracted a tarball:

Percona Server 5.6.17 uses the following directory for plugins (I compiled it from source):

I think this is unnecessary for Percona to add an extra level of directories and it becomes incompatible with MySQL. Where can I report this potential bug?

When using Percona’s my.cnf file, MySQL community can’t start because it cannot find the path and thus the configuration file needs to be different:
2014-05-08 12:19:42 30925 [ERROR] Can’t open shared library ‘/mysql/06/server/lib/mysql/plugin/’ (errno: 0 /mysql/06/server/lib/mysql/plugin/ cannot open shared object file: No such file or directory)
2014-05-08 12:19:42 30925 [ERROR] /mysql/server/mysql-5.6.17-linux-glibc2.5-x86_64/bin/mysqld: unknown variable ‘validate-password=FORCE_PLUS_PERMANENT’
2014-05-08 12:19:42 30925 [ERROR] Aborting

Percona Server is suppose to be a drop in replacement for MySQL, so it should change this to match MySQL.
