Following up on my question from yesterday...

I've now had a chance to check the aria2 sources and evidently it now
requires C++11 support, which I find surprising, but that's progress I
suppose...

I've just noticed for lang/clang-devel, the actual clang binary has
been recently renamed to clang-devel, but this isn't mentioned in
/usr/ports/UPDATING.

If I set CXX=clang++-devel in make.conf, the aria2 configure script
still fails though, complaining of missing C++11 support. Odd.

On a hunch I tried reinstalling textproc/py-sphinx, which failed with
the same error. Evidently py-sphinx is missing a dependency on
textproc/py-MarkupSafe. Once markupsafe is installed I could build &
install llvm33 & clang33.

But even so, the aria2 build still complains about missing C++11 support:

checking whether /usr/local/bin/clang++33 supports C++11 features by default... no

configure: error: *** A compiler with support for C++11 language features is required.
===>  Script "configure" failed unexpectedly.

Any suggestions?
