So host needs to install terminfo-dev. How is that different from the host environment needing to provide other pieces of the development environment? For example if another tool needed openssl-dev, would we disable crypto? Or if it needed yacc/bison or autoconf/automake wouldn't we rather install those? Isn't simple to type one command to install the appropriate packages?
