I don't think we can count on C++ 11 on all of our supported platforms yet, but that day is coming and I'd love to drop any externals that we can.
I'd love to get rid of boost in particular, but building the python bindings isn't really optional for us. So that's sort of moot. I would certainly look at a patch to remove pcre or boost dependency, but I can't promise to take it into the mainline at this time.

BTW, Is there a reason to not rip out the PCRE dependency and just do the matching with C++11 regex? If I spent some hours making a patch to do this would it be accepted? None of the "perl compatible" features are actually used and it looks to be a simple port of a couple dozen lines.
Similarly, with regard to Boost from a quick glance all that seems to be in use are Boost's smart pointers and the Python bindings. It would probably be best to simply replace the Boost smart pointers with C++11 smart pointers. Then the build system should have zero Boost dependency unless the Python bindings are enabled. Would such a patch be accepted?
