[vbox-dev] Parallel build failure

came accross this trying to install VirtualBox 4.0.12 on a Gentoo Linux box 
with a triple core Phenom and the build settings configured to run several jobs 
in parallel.  As usual with such parallel build failures, the error is 
somewhat reproducible, but not reliably so.
In this case, two attempts failed while the third build completed 
successfully.  I then remembered that I had the same problem with 4.0.10 and 
then worked around by forcing a fully serialized build via MAKEOPTS=-j1
Looks like there are some missing dependencies on cr_pixeldata.h and 
presumably other generated files.

Here's the relevant part of the build output,  I'll gladly provide a full log 
if neccessary:

In file included from /var/tmp/portage/app-
                 from /var/tmp/portage/app-
                 from /var/tmp/portage/app-
error: state/cr_statefuncs.h: No such file or directory

Kind regards,
