This is one of the major defects in the current MacPorts implementation
IMHO. There really ought to be a way to have co-existing mpfr-shlibs
packages for 2.x and 3.x but conflicting mpfr packages for building
programs against. We have exactly the same issue with molmol in
MacPorts. It is incompatible with the current openmotif 2.3.x releases and
needs co-existing openmotif-shlibs packages for 2.2.x and 2.3.x so
that molmol can be built and run against openmotif 2.2.x.
