Books not building on fresh checkout

[Russell Haley]

Hi,

I'm getting a build error on a fresh checkout. My base directory is
~/freebsd. This is the same error that stumped me some months back.
Any advice would be grand. As follows:

mkdir docs; svn co https://svn.freebsd.org/doc/head/ docs/

cd docs/en_US.ISO8859-1/books/porters-handbook/

russellh at russell ~/f/d/e/b/porters-handbook> make
