'gem install linecache' fails on RHEL 7.1 LE and Ubuntu 14.04 on ppc64le arch

[SriramaSharma]

I tried installing linecache gem using command : 'gem install linecache'.
The install fails with below error:

root# gem install linecache
Building native extensions.  This could take a while...
ERROR:  Error installing linecache:
ERROR: Failed to build gem native extension.

/usr/bin/ruby2.1 extconf.rb
Can't handle 1.9.x yet
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:
        --with-opt-dir
        --without-opt-dir
        --with-opt-include
        --without-opt-include=${opt-dir}/include
        --with-opt-lib
        --without-opt-lib=${opt-dir}/lib
        --with-make-prog
        --without-make-prog
        --srcdir=.
        --curdir
        --ruby=/usr/bin/ruby2.1

extconf failed, exit code 1

Gem files will remain installed in /var/lib/gems/2.1.0/gems/linecache-0.46 for inspection.

I think this project has been abandoned. I could also not get this to install. The debugger-linecache fork installs fine for me though
gem install debugger-linecache
