Try the patch below, or use the CVS version.

Yes.  Since the configure script is generated automatically, there is
no reason to have it in the CVS archive.  You need to run the
autogen.sh script first, then run configure and make.  You'll need
autoconf 2.5x.  You'll also need gperf, flex, and bison to complete
the build.
