Problem with installing MySQL from package

[Jaroslav Prodelal <prodelal@oldany.cz>]

Hi,

   I want to install MySQL from package by command:

		pkg_add -p /usr/local/mysql mysql-server-3.23.42-max.tgz

and it writes me:
		pkg_add(mysql-server-3.23.42-max): add of dependency 'pth-1.4.0pl1' 
failed

What should I do?

Thanks

Kaido
