How to plot a "circle" on a map with a radius given in meters

I would like to plot the locus of points equidistant from a point on a sphere. Any suggestions on how to do this?

project module would allow you to achieve that.

The attached shell script (pt.txt) shows a really cludgy way I computed the coordinates of 10 m circles which I used for making Tissot’s indicatrices. Maybe you can extract something from this?
