kernel compile fails with error 1

[Nathanael Schweers]

Hi folks,
I'm quite new to FreeBSD and mailing lists, so I hope not to be inpolite.
I've been using Gentoo Linux for a while and really like it, and now I'm 
giving FreeBSD a try.
I have switched to stable ( is there a difference between 6.1-STABLE and 
6.2-PRERELEASE?) and I managed to successfully compile and run a GENERIC 
kernel, but when I try to compile my own kernel make aborts with an 
error 1. Here the last bit of output:

make -V CFILES -V SYSTEM_CFILES -V GEN_CFILES |  MKDEP_CPP="cc -E" 
CC="cc" xargs mkdep -a -f .newdep -O -pipe  -Wall -Wredundant-decls

I find it quite strange that make stops with the nve module, as the 
GENERIC compiles, and I've got an nVidia nForce2 ethernet chip onboard.
Thx for any help.
