I got an error building stage3 while emerging libxml2-2.7.7:

My stage*.spec:

Stage1:
subarch: i686
target: stage1
version_stamp: kmdevelop-20100514
rel_type: default
profile: default/linux/x86/10.0/desktop
snapshot: 20100514
source_subpath: default/stage3-i686-20100511

Stage2:
subarch: i686
target: stage2
version_stamp: kmdevelop-20100514
rel_type: default
profile: default/linux/x86/10.0/desktop
snapshot: 20100514
source_subpath: default/stage1-i686-kmdevelop-20100514

Stage3:
subarch: i686
target: stage3
version_stamp: kmdevelop-20100514
rel_type: default
profile: default/linux/x86/10.0/desktop
snapshot: 20100514
source_subpath: default/stage2-i686-kmdevelop-20100514

Firstly I though It could be that I was building stage1 with no
desktop profile, so xml USE flag wasn't active, but after building
again with desktop profile this error stays.
