After this error I empty's /usr/src and /usr/ports I can compile the kernel and install the kernel. But a "make buildworld" gives the above error. Copying libc.a and libc32.a from another machine didn't solve the problem. Can you give me another clue? Is it possible to reinstall world from a nightly snapshot without destroying the running system (I'm using the ZFS file system with a pool of 4 HDD) Thanks Jack
