Comment (by egall@…):

 Replying to [comment:3 cal@…]:
 > Can we instead prevent gawk from linking with gmp and mpfr and avoid the
 dependency? I really don't think we need arbitrary precision arithmetics
 in gawk and it adds a dependency a lot of people will have to install.

 How about making it a variant? I agree that since gawk is usually one of
 the first ports that I install on a new install of MacPorts, I would also
 prefer that its dependency list be kept short, but only for the first time
 that I install it. After I have my normal list of ports installed, it
 might be nice to then be able to experiment with gawk's gmp/mpfr support
 by installing it with a new variant.
