Subject: requires() fails if the requirement has dependencies.
The attached Makefile.PL and output illustrates the problem. When using MI, if your dependencies have unresolved dependencies the build for the dependency is considered a failure. This does not occur when simply installing the dependency under the CPAN shell. In my environment I do not have File::Find::Rule nor Number::Compare installed to trigger the bug. I've tried it also on Test::Dependencies (lacking it and File::Find::Rule) and JSAN::Client (lacking it and HTML::Location). I noticed this bug because I am unable to install anything which depends on Test::Dependencies without first manually installing TD. This includes Class::Accessor::Named.

PS CPAN shell 1.87 MakeMaker 6.30. perl 5.8.6
The problem only occurs if the Makefile.PL is run from the command line. Otherwise AI allows the CPAN shell to do the installation and everything runs fine. PS CPANPLUS is not installed.
Fixed it. The issue is that the docs lie. CPAN::Shell->install($module) is not the same as CPAN::Shell->expand(Module => $mod)->install. CPAN::Shell->install is different from CPAN::Distribution->install. See 21144. The fix is to have AutoInstall use CPAN::Shell->install. Jesse has given me commit rights on the modinstall openfoundry repository so I'm going to commit this. --- lib/Module/ (revision 17334) +++ lib/Module/ (local) @@ -465,9 +465,9 @@ delete $INC{$inc}; } - $obj->force('install') if $args{force}; - - my $rv = $obj->install || eval { + my $rv = $args{force} ?

Closed as this patch has already been applied. Thanks.
