Bug #60859 the crash server for labs-innodb-memcached-log after installation

Description:
after install plugin crush server:

mysql> install plugin daemon_memcached soname «libmemcached.so»;
Query OK, 0 rows affected (0,00 sec)

mysql> 110414 01:46:32 mysqld_safe mysqld restarted
110414 01:46:32 mysqld_safe mysqld from pid file /usr/local/mysql/data/akalend.local.pid ended

The errorlog:

We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.

How to repeat:
I repeat installation two time.

Sorry for the confusion. For the labs release, Linux is the only platform we have tested. Other binaries should not be on the download page.

This is also explicitly written at http://blogs.innodb.com/wp/2011/04/get-started-with-innodb-memcached-daemon-plugin/:

"Currently, the Memcached Daemon Plugin prototype is only supported on Linux platform. And as a prerequisite, you must have libevent installed, since it is required by memcached."
