error installing (or compiling) eventmachine-1.0.0.beta.3 rubygem

due to rubygem dependencies, eventmachine version 1.0.0.beta.3 needs to be installed. installing the rubygem as follows, results in error. enclosed a snippet for convenience.

$ sudo gem install eventmachine -v '1.0.0.beta.3'

i tried to modify /var/lib/gems/2.0.0/gems/eventmachine-1.0.0.beta.3/ext/Makefile by replacing -Werror=format-security with -Wformat-security, then running make. it installed the the rubygem, though when trying to check whether the rubygem installation has a consistent behaviour. hence, i tried to invoke the command above (gem install...) again, but it fails again.

here are few more details on the system:

$ ruby --version
ruby 2.0.0p299 (2013-08-29) [x86_64-linux-gnu]

$ cat /etc/*release* | grep -i distrib

$ uname -a
Linux user 3.11.0-15-generic #23-Ubuntu SMP Mon Dec 9 18:17:04 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

$ gcc --version | grep gcc
gcc (Ubuntu/Linaro 4.8.1-10ubuntu9) 4.8.1

i am also familiar with this fix solution, and this one, but it does not work for me. any help would be appreciated.

UPDATE:

i also tried the following:

Apparently this is an issue with em-winrm depending on eventmachine v1.0.0.beta.3.

A combination of mudasobwa's comment and workaround suggested here worked for me:

gem install eventmachine -v '1.0.0.beta.3' -- --with-cflags=\"-O2 -pipe -march=native -w\"

Alternatively, if you wish to use bundler

export CONFIGURE_ARGS="--with-cflags='-O2 -pipe -march=native -w'"
bundle install --path vendor
