Can't install gems using Cygwin -- undefined reference to `libiconv'

I'm getting the following output when trying to gem install awsudo:

The mkmf.log has:

--------------------

But I'm not really sure what to make of it. I'm using Cygwin for this; not sure what to do next.

My suggestion would be to run cygwin-setup.exe / use apt-cyg to install libiconv-devel package

and rerun bundle install awsudo

Just a guess. I believe I encountered a similar issue while installing nokogiri with native extensions. Unfortunately, I don't have access to the system now to look at the logs to get the specific details. HTH
