error running 'requirements_centos_libs_install libyaml-devel readline-devel libffi-devel sqlite-devel', showing last 15 lines of /usr/local/rvm/log/1439995406_ruby-1.9.2-p330/package_install_libyaml-devel_readline-devel_libffi-devel_sqlite-devel.log if don't want/need both architectures anymore can remove 1 missing update , work.

you have duplicate versions of libffi installed already. can use "yum check" yum show these errors.

...you can use --setopt=protected_multilib=false remove checking, never correct thing else go wrong (often causing more problems).

protected multilib versions: libffi-3.0.5-3.2.el6.i686 != libffi-3.0.9-1.el5.rf.x86_64 ++ return 1 ++ return 1 requirements installation failed status: 1.

i try remove lib again fail :

error: trying remove "yum", protected

can explain fail? please! thx all!

p.s. i'm update system (in case if answer "yum update") :)

try remove lib : 

rpm -e --nodeps libffi

and again try install ruby.
