why so many errors with ports??

[Giorgos Tsiapaliokas]

hello,

i am coming from the linux world i was a gentoo user and i have install on
my second machine FBSD,i have made many formats but every time i try to
install a graphical enviroment (such as xfce,kde) many many errors come up.
i have heard that the ports are more stable than portage but with portage i
didn't have so many errors (actually i can't recall a time when portage
"died")

am i doing sth wrong or ports comes up with many errors??


P.S.: 1 week not i haven't manage to install a graphical enviroment


thanks in advance
