perl Buil.PL gives confusing error message when Module::Build not installed

[Kake]

If you have Config::Tiny installed but don't have one of Module::Build and Class::Accessor, the error message you get from 'perl Build.PL' is confusing:

"Config::Tiny is required to configure this application."

[andrewb]

my feeling is that it is trying to be helpful but it can't do so.

eval {
    require Config::Tiny;
};
die "Config::Tiny is required to configure this application.\n" if $@;

Looks OK

eval {
    require OpenGuides::Build;
    require OpenGuides::Config;
};
die "???? is required to configure this application.\n" if $@;

isn't going to work as the problem is one of a number of modules called by OpenGuides::Build.

We could do

die "£@" if $@;

I would be inclinded just do to

use OpenGuides::Build;
use OpenGuides::Config;

And make it truthful rather than friendly (and loosing information)
