Messed '%s' value

Indeed %s used to default to the final install location, but that could be overridden in 0.16 with the alien_stage_install option, and then in 0.17 alien_stage_install became the default. I've got a PR that updated the documentation.

To get the original behavior you can set alien_stage_install to 0. However, be aware that relies on so called blib detection; a method of determining if the Alien is being installed using a long list of blib paths in PERL5LIB, which is common in cpantesters. This detection is unfortunately inherently unreliable, and apparently buggy because I also fixed a bug in it when I was looking into this issue.

The recommend route if you need to run ./configure with the final install path is to use Alien::Build which has a more reliable system by which it stages files for install. Alien::Build also has other advantages and fewer prereqs so it isn't a bad upgrade to make anyway. Both ABMB and Alien::Build use the same runtime (Alien::Base) so the interface once the alien is installed wouldn't change.

1.07 has both the documentation and the bug fix.

This alienfile does at least some of what the Build.PL for Alien::ImageMagick is doing. I'm not sure that it should be setting --exec-prefix so I took that out. It's not patching anything, but it might be a start.

use alienfile;
use Config;

plugin 'PkgConfig' => (
  pkg_name => 'MagickWand',
);

share {

  start_url 'http://www.imagemagick.org/download/ImageMagick.tar.gz';
  plugin 'Download';
  plugin 'Extract' => format => 'tar.gz';

  my $use_threads = $Config{usethreads} ? '' : '--without-threads';
  my $enable_shared = ( ( $Config{useshrplib} || '' ) eq 'false' ) ? '' : '--enable-shared';

  meta->prop->{env_interpolate} = 1;
  meta->prop->{env}->{LDFLAGS} = "-L%{perl.config.archlib}/CORE";

  plugin 'Build::Autoconf';

  build [
    "%{configure} --with-perl=%{perl} $enable_shared $use_threads",
    '%{make}',
    '%{make} install',
  ];

};

Hi.
I understand the reason of using %s as blib, but in fact that was not clear. To have two different variables might be useful? Well, its an idea.
ImageMagick has a flag to configure the datadir, and for the bug I was trying to solve, it did the trick.
Thank you for your time and help.
Best,
Alberto

I suppose different variable name would have been possible, and might have been a little more clear. It's really change in behavior though, and the old behavior was problematic. The fact that that part of the documentation didn't get updated was an oversight.

👍 great.
