The previous commit, r475448, didn't upgrade the port from 3.1 to 3.3.2.
GH_TAGNAME should have been modified as part of the change.
In order to upgrade from 3.1 to 3.3.2, add an upstream patch from @bcran for
src/util.c to add #include <netinet/in.h>.
While here, add pump support/fix the pump disable option by passing the proper
configure flag when pump support is disabled.
Finally, use the upstream install target for distcc and cherry-pick pieces that
were installed previously, plus ones related to the optional pump support.
