You can install this using in the usual Perl fashion:
perl Makefile.PL
make
make test
# (or) env MQHOST="localhost" make test
make install
The documentation is in the module file. Once you install the file, you can read it with perldoc.
perldoc Net::RabbitMQ
If you want to read it before you install it, you can use perldoc directly on the module file.
perldoc RabbitMQ.pm
