"make installworld" :-)

The proper way to get rid of outdated files is 'make delete-old-files'.

However, if you've borked this system, you may be able to get things
back with a 'make includes' but that can fail at times due to
dependencies on /usr/include that creep in.  You may have to define a
lot of WITHOUT_FOO variables.

You may be able to install the tarballs from a release that includes
the includes to recover...  You may need to say OSRELDATE=0 on the
command line to successfully build.
