I use this script to search for dependencies:

#!/bin/sh

for i in *; do
if [ -d $i ]; then
  cd $i
  echo $i:
  cat configure.ac | grep PKG_CHECK_MODULES | sed -e
's/.*PKG_CHECK_MODULES([A-Z0-9]* \([a-z0-9_\$A-Z]*\).*/\1/g'
  echo
  cd ..;
  fi;
done

I don't see any listed dependencies for the proto modules.
