This file is a symbolic link:
lrwxrwxrwx root/root         0 2013-08-24 08:09
zeromq3-x-master/doc/zmq_epgm.txt -> zmq_pgm.txt


I don't have any trouble using
cmake version 2.8.11.20130914-g396df-dirty
(git master)

Q1) Do you do the extraction on Windows or Linux?
       If you are on Windows then this is the "well-know" trouble
       of "unsupported" lilbarchive feature on Windows.
       Dig the CMake ML and/or libarchive tracker and you'll find out.

Q2) Is your CMake compiled with "system libarchive" or the one thar
comes with CMake ?
