Forum OpenACS Development: Re: Res: Re: invalid command name "template::head::add_style"

I just got install OpenAcs 5.4.3 and I did install the ajaxhelper and I test it whit a few test scipt and the result was fine, but I just download a package application "organization" from the Portal de software publico brasilero because I want to see the another scripts. I want to know if I have to install another package like ajaxhelper or just installing the new version of openacs 5.5 it install all the package and I don´t have to install individually.

sorry for my bad English
