Hi! Thanks for the report. Other folks have also encountered this,
and it appears to be a problem with distro packaging of the gcc plugin
development packages. You'll need to install the GNU multiprecision
libraries ("gmp-devel" on most rpm-based systems, "libgmp-dev" on most
debian systems)[1].
Hopefully that'll work!
