Silent failure on gem install

[Tim Uckun]

I have a case of silent failure when trying to install gems with
native libraries. It runs the gem install command which fails because
the dev libraries are not in place but the install command returns
true and the gems are not installed.

is there a way to force the package manager to raise an exception when
anything can't be installed?


package_manager.install <<-HERE, :with => :gem, :docs => false
ruby-pg
postgres
HERE


This is the output

+suitability+ method
