Try the multiple ways to setup the extension

  $ hg -R server log --config 'extensions.evolve.serveronly='
  $ hg -R server log --config "extensions.evolve.serveronly=${SRCDIR}/hgext3rd/evolve/serveronly.py"
  $ PYTHONPATH=$HGTEST_ORIG_PYTHONPATH hg -R server log --config "extensions.evolve.serveronly=${SRCDIR}/hgext3rd/evolve/serveronly.py"

setup repo

  $ hg serve -R server -n test -p $HGPORT -d --pid-file=hg.pid -A access.log -E errors.log
