Install enough to get Ruby and Sass working on RHEL/CentOS

install-ruby.sh

# lol redhat
su

# Install deps
yum install libyaml libyaml-devel openssl libxml2-devel bison libxslt-devel openssl-devel tcl tk libffi tcl-devel tk-devel libffi-devel

# Download Ruby
cd /usr/local/src/
wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p392.tar.gz
tar -xvzf ruby-1.9.3-p392.tar.gz
cd ruby-1.9.3-p392

# Compile Ruby from Source
./configure
make
make test
make install
ruby -v

# Install things for SASS
gem install bundler
gem install sass
gem install listen
gem install rails            # well.. it was worth a try!

required on the "yum install make"

This doesn't work on red hat 7. I get compilation error! have you tried it on red hat 7?

Here is one of the errors:

ossl_pkey_ec.c:816:29: error: ‘EC_GROUP_new_curve_GF2m’ undeclared (first use in this function)
new_curve = EC_GROUP_new_curve_GF2m;

yum install ruby
gem install sass
gem install bundler

This works for me - Centos 7

It doesn't work on CentOs 7.1.
It goes all well until I make make
