Comment:

 In aria2 @1.18.0 the developers changed the configure script to check for
 and use libc++ automatically if needed. The port builds successfully this
 way on Lion and later. The problem is on Snow Leopard and earlier, where
 OS X does not include libc++. On those systems, users need to follow part
 of the instructions in LibcxxOnOlderSystems: namely, install the libcxx
 port.

 The port behaves somewhat unexpectedly, in that it does not clean up after
 itself if you deactivate or uninstall it. I've filed #49903 to request it
 be improved to do this. Once it does, it would be a simple matter to
 modify the cxx11 portgroup to add a dependency on the libcxx port when
 needed, and to modify the aria2 port to use that portgroup.
