Trying to build the kernel I get the following failure:

time make -j8 buildkernel KERNCONF=MYKERNEL

I tried this 4 times, twice with MYKERNEL and twice with GENERIC.  It 
failed in the same spot every time.  Is anyone else seeing this?

Also, I tried without -j8, and it fails with the following:

Here is /etc/make.conf

# cat /etc/make.conf
OVERRIDE_LINUX_BASE_PORT=f10
QT4_OPTIONS= QGTKSTYLE
WITH_OPENSSL_PORT=yes

The kernel previously built without problems with this same configuration.
