portupgrade and packagesite

[Osmany Guirola Cruz]

Hi people....
I am trying to upgrade my gtk20 and i do the following                                                                                         
#setenv PACKAGESITE 
ftp://ftp1.freebsd.org/pub/FreeBSD/ports/i386/packages-5-current/                                                                                                                                                                      

and then 

#portupgrade -PP gtk
and this is what happens
fetch: ftp://ftp1.freebsd.org/pub/FreeBSD/ports/i386/All/gtk-2.4.9_1.tbz
fetch is tryin to download the packages from an incorrect path
What am i doing wrong?
