Thing is, there should be no need to enforce timetamps to get a 
successful build out of the box.

One of the purpose of using autoconf is to ensure that all required 
dependencies (including tools) are available.

So either you should consider the man pages as generated files (which, 
indeed, they are) and make latex2man required, or else make latex2man 
optional using a configure option (that's what my proposed patch does).
