It isn't in the 5.0.2 binary packages. The source code is in the 5.0.2
source packages and the CVS release branch, but the build system
doesn't have the necessary extensions.

Whereas the rest of GRASS is written in C, r.terraflow is written in
C++. This required some extensions to the build system; in turn, it
was decided (by me, primarily) that this was too controversial for
5.0.2 (i.e. the small risk of breaking everything outweighed the
benefits of one additional module).

If you want r.terraflow, you can either try building it manually (i.e. 
hacking src/CMD/*) from the 5.0.2 source, or obtain the development
version from CVS (which has the necessary changes to configure etc;
you have to specify the --with-cxx switch in order for r.terraflow to
be built).
