I am trying to install Pinba engine with Percona Mysql Server 5.5.

Everything went fine except plugin installing. I got the following error message:

ERROR 1126 (HY000): Can't open shared library '/usr/lib/mysql/plugin/libpinba_engine.so' (errno: 2 undefined symbol: _db_enter_)

Does anybody knows what the problem with my plugin?

Yeah, I know.
And MySQL guys know: http://bugs.mysql.com/bug.php?id=60872
But when it comes to real code and patches, they just shut up and start looking the other way like nothing happened.

Please try recent Pinba snapshot and don't use --enable-debug when building Pinba with non-debug MySQL -
that's the only way to fix this problem at the moment.

The .so seems to be broken and/or built in a wrong way.
In any case, lib_mysqludf_sys.so does not have anything to do with Pinba.
