I'm getting an error "autoheader: not found" - what's wrong?

This usually appears when compiling the current development source version, obtained via CVS. Unfortunately, the timestamps on some of the configure files are such that make assumes (mistakenly) that the configure script needs to be re-generated. A similar problem may arise relating to 'autoconf'.

In both cases, this can be corrected by running the command "make -k touchit" before attempting to make the main package.
