Update (with thanks to Craig Barnes!):
all that was missing was an "ldconfig" to make the new library in
/usr/local/bin/ be recognized... this works:

 (eepitch-shell)
 (eepitch-kill)
 (eepitch-shell)
  rm -Rfv ~/usrc/gumbo-parser/
  cd      ~/usrc/
  git clone --depth 1 https://github.com/google/gumbo-parser
  cd      ~/usrc/gumbo-parser/
  sh ./autogen.sh
  ./configure
  make
  sudo make install
  sudo ldconfig

  rm -Rfv ~/usrc/lua-gumbo/
  cd      ~/usrc/
  git clone --depth 1 https://github.com/craigbarnes/lua-gumbo
  cd      ~/usrc/lua-gumbo/
  make
  make check
  sudo make install

  lua5.1
    parse = require("gumbo").parse
    print(parse("<title>Hello  world!</title>").title)

Cheers! =)
