So installieren Sie Monkeysphere unter OSX El Capitan

Ich habe versucht, Monkeysphere über Homebrew zu installieren, aber es klagt über eine nicht erfüllte Abhängigkeit.

monkeysphere: Unsatisfied dependency: Crypt::OpenSSL::Bignum
Homebrew does not provide Perl dependencies; install with:
   cpan -i Crypt::OpenSSL::Bignum
Error: An unsatisfied requirement failed this build.

Also habe ich versucht, den oben genannten Befehl auszuführen und gegen Ende kommt es zu Fehlern.

Writing Makefile for Crypt::OpenSSL::Bignum
Writing MYMETA.yml and MYMETA.json
cp Bignum/CTX.pm blib/lib/Crypt/OpenSSL/Bignum/CTX.pm
cp Bignum.pm blib/lib/Crypt/OpenSSL/Bignum.pm

Ich habe es so zum Laufen gebracht

#configure perl
sudo perl -MCPAN -e shell
perl> o conf init
#update perl (this takes a while)
sudo perl -MCPAN -e 'install Bundle::CPAN'
#link openssl
brew link openssl --force
#installing this dependency that monkeysphere was originally complaining about
cpan -i Crypt::OpenSSL::Bignum
#installing monkeysphere
brew install monkeysphere
