Error compiling current kernel

[Riccardo Mottola <riccardo.mottola%libero.it@localhost>]

Hi,

when i try to compile my kernel (which is an old configure which i carry 
on and on) I get:
===> Building kernel:     nc6120
===> Build directory: /usr/src/../obj/sys/arch/i386/compile/nc6120
(cd /usr/obj/sys/arch/i386/compile/nc6120 && rm -f a.out [Ee]rrs mklog 
core *.core .gdbinit || true)
/usr/src/sys/arch/i386/conf/nc6120:1222: `ral' cannot attach to `uhub'
*** Stop.


I suppose that there are new dependencies inside the options or new 
options. Since the configuration is "tuned" for my
laptop, what is the best way to update it?

Thank you,

Riccardo
