 aria2 fails to build on 10.6, because it requires C++11, and although it
 uses the cxx11 1.1 portgroup, which uses a newer clang, it still uses the
 old Xcode ranlib which doesn't understand the files produced by that new
 clang:

 {{{
 /bin/sh ../libtool  --tag=CC   --mode=link /opt/local/bin/clang-mp-5.0
 -Wall -pipe -Os -arch x86_64 -no-undefined -version-info 0:1:0
 -L/opt/local/lib -Wl,-headerpad_max_install_names -lintl -arch x86_64 -o
 libwslay.la   wslay_frame.lo wslay_event.lo wslay_queue.lo wslay_net.lo
 libtool: warning: '-version-info/-version-number' is ignored for

 /usr/bin/ranlib: object: .libs/libwslay.a(wslay_frame.o) malformed object

 ar: internal ranlib command failed
 }}}

 Perhaps the portgroup should have a dependency on cctools, which provides
 a newer ranlib.
