This usually happends when Ruby wants to build a gem (usually first one) from source and it requires a C compiler. This can also happen when you try to compile a piece of software from source and that software is written in C. Usually you will have some sort of Makefile and will ask you to run make install etc. This is when the error can occur.
To fix this all you need is to install a C compiler. GNU Compiler Collection includes compiler for C. The package can be installed using the following command on a CentOS machine utilising yum.

sudo yum install gcc
