Actually it's silly, this archive_read_open_filename function appeared
between 1.2.38 and 1.2.57, the two only 1.2.x releases left there :
http://people.freebsd.org/~kientzle/libarchive/src/
That 1.2.53 version this guy was using on debian doesn't even exist
anymore. And that's indeed the version debian stable is using.
(testing has 2.4.11 and unstable has 2.4.17).

I don't know if pacman would work with 1.2.57 :P
