           Summary: installation fails with confusing error message if DNS
                    is not set up for localhost
           Product: Koha
           Version: HEAD
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Installation (command-line installer)
        AssignedTo: galen.charlton at liblime.com

It seems that if you don't have DNS set up for your hostname, installation
fails with this confusing error message:

   Bad arg length for Socket::inet_ntoa, length is 0, should be 4 at
rewrite-config.PL line 67.
   make: *** [blib/KOHA_CONF_DIR/koha-conf.xml] Error 255

It seems that we would be better off checking for this condition earlier and
printing a more useful error message. Jesse suggested this check:

$ perl -e 'use Sys::Hostname; use Socket; print hostname() . "\n"; print
gethostbyname(hostname()) ? "dns good\n" : "dns bad\n";'

Can we stick that somewhere like in the Makefile.PL?
