Updated the check for gettext introduced in r12475 to also look at the version.

import os

import re

from subprocess import Popen, PIPE

def find_command(cmd, path=None, pathext=None):

    if path is None:

# checks if it can find xgettext on the PATH and

# imports the extraction tests if yes

if find_command('xgettext'):

xgettext_cmd = find_command('xgettext')

if xgettext_cmd:

    p = Popen('%s --version' % xgettext_cmd, shell=True, stdout=PIPE, stderr=PIPE, close_fds=os.name != 'nt', universal_newlines=True)

    output = p.communicate()[0]

    match = re.search(r'(?P<major>\d+)\.(?P<minor>\d+)', output)

    if match:

        xversion = (int(match.group('major')), int(match.group('minor')))

        if xversion > (0, 15):

            from extraction import *
