When you build world, you first spend a lot of time building a new
toolchain using your systems' installed toolchain. This new toolchain
is what appears to be broken in the output you show.
So, you may well have a perfectly good toolchain installed, but a source
tree that is defective -- mistakes do happen, and it can break building
the world.
In this case, you can do the following to give yourself the best chance
of building world successfully again:
* delete everything under /usr/obj
* check out the most recent sources using git or svn or svnlite or
whatever you prefer
* restart the build
Check the output from your buildworld and buildkernel for any errors and
don't install unless the compile was error free.
Consider whether 13-CURRENT is the right version for you to run. It is
a development version and is not guaranteed to run correctly (or at
all). You're expected to be able to cope with such problems when you
run it. You will find -STABLE or -RELEASE a smoother ride and more
performant to boot, as those code branches have certain performance
impacting debugging code turned off.
Cheers,
Matthew
