I have no idea what conda is or how it works.  I assume it's on some
kind of Linux system?

The simplest thing is to comple the GMP and MPFR libraries from
source and install then and then compile gawk from source with the
standard configure and make recipe.

If you're on a Linux system with gawk already installed, maybe it was
compiled with MPFR support already?  The output of gawk --version will
show you the MPFR and GMP versions if so.
