To enable support for Software Collections on your system so that you can enable and build Software Collections, you need to have installed the packages scl-utils and scl-utils-build.
If the packages scl-utils and scl-utils-build are not already installed on your system, you can install them by typing the following at a shell prompt as root:
yum install scl-utils scl-utils-build
Depending on the subscriptions available to your Red Hat Enterprise Linux system, you may need to enable the
Optional channel to install the scl-utils-build package.
