Installation Coldfusion error

[misterm]

Hello with all, when I install coldfusion under debian according to Howto of this URL "http://www.howtoforge.com/coldfusion_installation_debian_sarge", I have an error at the time of the installation of this one, then, I have reinstalment coldfusion in "Multiserver configuration", is I realized that that functions, because when you make an installation "Server configuration", it put an error "Jrun error", that want to say that it is necessary that jrun is to install.
