There is no make check target in the standard Makefile. You mean "make
test".
You can eliminate the asking about installing dependencies with a CPAN.pm
configuration parameter. It was one of the questions when you first ran
cpan:
The CPAN module can detect when a module which you are trying to build
depends on prerequisites. If this happens, it can build the
prerequisites for you automatically ('follow'), ask you for
confirmation ('ask'), or just ignore them ('ignore'). Please set your
policy to one of the three values.
You can set it now to build prerequisites automatically with
o conf prerequisites_policy follow
You can eliminate additional questions with
o conf build_requires_install_policy yes
However you cannot stop modules from asking questions during their
Makefile.PL or Build.PL if they want.
To install many modules with a single command, use a bundle:
