How do I make perlbrew install a specific development perl version (ie not perl-bleed)

Question

I'm trying to install a development perl version other than perl-bleed with perlbrew eg:

$ perlbrew install perl-5.21.5

fails if I tail the log file I see

$ tail ~/perl5/perlbrew/build.perl-5.21.5.log
    Data corruption and crashes are possible.

    It is most seriously suggested that you do not continue any further
    unless you want to help in developing and debugging Perl.

    If you *still* want to build perl, you can answer 'y' now,
    or pass -Dusedevel to Configure.

Do you really want to continue? [n]  
Okay, bye.

How can I tell perlbrew to answer yes?

你需要将-Dusedevel传递给-Dusedevel ，例如：

$ perlbrew install perl-5.21.5 -Dusedevel
