# mpfr is special because we cannot break ABI without first rebuild gcc.
# so we need be able to have multiple version of mpfr installed in parallel
# we also need be able to calculate bulid order from global scope, otherwise
# it is not possible to calculate build order til after package is built.
# Therfore we call -dev package mpfr-dev instead of mpfr4-dev with a
# provides=mpfr-dev
