encfs @1.8.1: A compiler with support for C++11 language features is required.

[gerd.simon.schmidt@…]

I tried to upgrade my outdated ports, which include encfs. The port upgrade encfs stopped with the following error:

:info:configure checking whether /Developer/usr/bin/llvm-g++-4.2 supports C++11 features by default... no
:info:configure checking whether /Developer/usr/bin/llvm-g++-4.2 supports C++11 features with -std=gnu++11... no

I found a similar error under the ticket #40494 for the aria2 package. The complete log file is attached.

Ah, then we should have this port use the cxx11 1.0 portgroup.

the same problem here (01/01/2016):

# port version 
Version: 2.3.4

# sw_vers 
ProductName:	Mac OS X
ProductVersion:	10.8.5
BuildVersion:	12F2560

I had to downgrade to version @1.7.5 (also boost to @1.56.0_1 with mpi.choose disabled in portfile)
