Good idea.
The patch looks fine.
You're welcome to push that as-is, or ...
What do you think about suggesting with each how to install
the missing package, e.g.,
You can install the required libgmp.* files
via "yum install gmp-devel" on a fedora-based system,
or "apt-get install gmp-devel" on a debian-based system.
The easier we make it for people to discover which libraries are
required/recommended and to install them, the more often people will use them.
No big deal, though.
