Description

nco fails to build on 10.7. There are undefined symbol errors relating to antlr:

Undefined symbols for architecture x86_64:
  "antlr::ASTFactory::create(int, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&)", referenced from:
      ncoParser::statement() in ncoParser.o
      ncoParser::block() in ncoParser.o
      ncoParser::lmt() in ncoParser.o
      ncoParser::lmt_list() in ncoParser.o

      ncoLexer::ncoLexer(std::__1::basic_istream<char, std::__1::char_traits<char> >&, prs_cls*) in ncoLexer.o
[snip]

I assume the problem is that nco is trying to link with libantlr, which is a static library. It was built back when libstdc++ was the default C++ standard library for MacPorts for 10.6-10.8, and now that we've switched to libc++ for 10.6-10.8, we need to rebuild antlr by increasing its revision. Do you agree?
