Module::Build and required packages not installed

pileofrogs has asked for the wisdom of the Perl Monks concerning the following question:

Hi, all ye Monks.

I'm using Module::Build and have done for years. One thing seems odd to me: If you don't have a required module, it displays a nice message, but it still exits with success. This means you can't do this:

perl Build.pl && ./Build && ./Build test && sudo ./Build install
[download]

... and have it do what you'd think it would do, namely stop after the 'perl Build.pl' stage noticed that the prerequisite modules aren't there.

I'm guessing either a) I'm doing something wrong and it should work that way or b) I'm doing something wrong by trying to use it that way.

So, if I want to install Module::Build packaged modules via a shell script, what's the best way to tell the shell script if the prerequisite modules are or aren't installed?

Thanks!

As of version 0.36, Module::Build comes with an `installdeps` action. So, you could do... `perl Build.pl && sudo ./Build installdeps && ./Build && ./Build test & +& sudo ./Build install` [download] You'll be asked if you want to install any missing dependencies (even optional ones listed in `recommends`).

In addition, before you run `./Build installdeps`, you can run `./Build prereq_report`. It'll list all requirements, minimum version required, the versions you have, and recommends.	[reply] [d/l] [select]
