Hi there,
Looking over your build log, I see in the output from configure
[quote]Checking for mysql_config … /usr/bin/mysql_config
Checking for libmysqlclient version >= 4.1.x … no (4.0.24)
[/quote]
That is, your libmysqlclient library is too old, and the root-plugin-mysql package cannot be build as it should. Please update to a newer version.
Yours,
Christian
