Jupyter notebook runs in my chrome browser and there are no proxy settings. I have enabled windows 10 original firewall. First I thought that the above error is due to the fact that jupyter is not running and installing Devel::IPerl might be requiring jupyter notebook instance running but this even has not resolved the issue. I decided to run cpan commands in jupyter notebook terminal tab in my chrome browser. Now I am using browser jupyter terminal tab for cpan commands. I again looked at the dependencies errors and found that for installing Devel::IPerl following dependencies are unmet. 
Warning: prerequisite IO::Async::Handle 0 not found.
Warning: prerequisite IO::Async::Loop 0 not found.
Warning: prerequisite IO::Async::Routine 0 not found.
Warning: prerequisite Net::Async::ZMQ 0.002 not found.
Warning: prerequisite Net::Async::ZMQ::Socket 0 not found.
Warning: prerequisite ZMQ::FFI 1.18 not found.

I tried resolving/installing one by one from top to bottom but every dependency required additional dependency or failed tests all with HTTP / connection /webserver sort of test fail errors. In last I tried installing ZMQ::FFI but it failed with following dependencies: 
Unsatisfied dependencies detected during ----
----       MLEHMANN/AnyEvent-7.17.tar.gz      ----
    Async::Interrupt [requires,optional]
    EV [requires,optional]
    Guard [requires,optional]

I then individually resolved all the above three dependencies installations and upon running "install AnyEvent" it generated following error where notable error is about test unable to make connection with host machine / network configuration error / environment variable setting etc.

So I believe the test failing is during some dependency installation which is unable to make connection with host machine. The error of Future:IO is at following .pm file line 194:
