RVM error while running make install. Error comes while installing power_assert gem

Im trying to install ruby 2.2.2 in my arch machine. When I run rvm install, I get the following error. Tried several times. Even removed rvm and re-installed. Still the same issue.

Same issue. This worked for me:

rvm get master
rvm reinstall 2.2.2

I used the head version of rvm before...
