MacPorts did a mass switch to libjpeg-turbo a couple of weeks ago [1].  AIUI, libjpeg-turbo is a drop-in replacement for libjpeg but with a massive (?) speed advantage.  Note that libjpeg-turbo installs the following dylibs:

$ port contents libjpeg-turbo |grep dylib
  /opt/local/lib/libjpeg.8.2.2.dylib
  /opt/local/lib/libjpeg.8.dylib
  /opt/local/lib/libjpeg.dylib
  /opt/local/lib/libturbojpeg.0.2.0.dylib
  /opt/local/lib/libturbojpeg.0.dylib
  /opt/local/lib/libturbojpeg.dylib

HTH,

Craig
