question -updating package + ignore depend

[mc]

hi,

can anyone briefly explain what is the general procedure here?

i am trying to update a few packages which inevitably provoke a firefox2 
install, which i don't want (have ff3).

checked google and porter's handbook, then tried marking ff2 as IGNORE -- 
which i didn't really understand how but added IGNORE= reason etc etc to the 
makefile at the very top after the comments. seems like it worked, but what i 
want to update fails because of that.

i am installing portupgrade now to try with k or K (whichever means comtinue 
anyway) but is this a good idea or an easier way?

also, i am not sure if questions like this go here or still go in ports 
mailing list ?

thanks in advance
