Rob Savoye has been so kind as to write the attached patch which 
correctly uses the standard configure option "--program-transform-name" 
to also rename the man pages.

After applying this patch, it is easy to prefix a 'g' to the front of 
any executable (and manpage) that does start with a 'z' by invoking 
configure as Matias suggested[1]:

  ./configure --prefix=/usr --program-transform-name='s/^z/g&/'

Thanks,
Antonio.
