[root@yster2 /usr/local/share/munin/plugins]# munin-run mysql autoconf
no (Missing dependency Cache::Cache)

So I install Cache::Cache

[root@yster2 /usr/local/share/munin/plugins]# cpan Cache::Cache
Loading internal null logger. Install Log::Log4perl for logging messages

Cache::Cache is up to date (1.08).

And try again:

[root@yster2 /usr/local/share/munin/plugins]# munin-run mysql autoconf
no (Missing dependency Cache::Cache)

No go.  What now?

# munin-run mysql suggest
Missing dependency Cache::Cache at /usr/local/etc/munin/plugins/mysql line 728.

This was working earlier, now it doesn't anymore.
