Comment (by kencu):

 mmm. Indeed, on 10.7 with the default setting of libstdc++, build of
 texlive-bin now fails with this:
 {{{
 In file included from pdftexdir/pdftosrc.cc:52:
 /opt/local/include/poppler/PDFDoc.h:295:153: error: use of undeclared
 identifier 'nullptr'
   void markPageObjects(Dict *pageDict, XRef *xRef, XRef *countRef, Guint
 numOffset, int oldRefNum, int newRefNum, std::set<Dict*>
 *alreadyMarkedDicts = nullptr);
 }}}

 I don't remember seeing this particular error before. This looks like
 something might have changed in poppler, and indeed it seems poppler was
 updated to 0.57.0 two days ago.  We're looking at a new error here now.

 Now that error can be solved by adding `-std=c++11` to the cxx build
 flags, but in doing so you run into this error later:

 {{{
 ./luatexdir/image/pdftoepdf.w:74:34: error: invalid suffix on literal;
 C++11 requires a space between literal and identifier [-Wreserved-user-
 defined-literal]
 snprintf(ck,PDF_CHECKSUM_SIZE,"%"PRIu64"_%"PRIu64,(uint64_t)size,(uint64_t)mtime);
                                  ^
 }}}

 All moving targets, eh? The cxx11 PortGroup is needed, but other
 adjustments will now be needed as well given the changes in poppler.

 Will need to dig in a bit to see a way through.
