2010-05-25 18:40:15: (critical) Running 'sh -c "ssh-keygen -l -f /etc/ssh/ssh_host_dsa_key.pub | awk '{print \"ssh:{\"$2\"}\"}'"' failed with the following message on stderr. Falling back to MAC address detection.

# find /opt/mysql/enterprise | grep libcrypto

How to repeat:
Start MEM agent on Ubuntu 9.04 and check the logs.

Suggested fix:
Use the correct libcrypto library.

Added note to changelog 2.2.2:
