While I don't have much help to get you fixed, I can tell you how this  
likely happened if you did a "make world" or "make installworld" at  
one point.

The installworld script is told that /lib/libc.so.x has to have a  
"chflags schg" applied to it, making it unchangeable. So when  
installing, it deletes the old libc, copies the new libc over, tries  
to do a chflags on it, fails because ZFS doesn't support flags, so it  
deletes libc and gives up.

libc is the first file that installworld tries to create using schg,  
so that's where it fails. The workaround is to do "make installworld  
NO_FSCHG=" so that it doesn't bother trying to set flags.
