[CentOS] server without gcc?

i cant believe i have a production box online without gcc installed using a
new CentOS 4 server CD???

confused to say the least as i always install all the compiler and etc
components...

will the command

yum install gcc

get me everything i need or should i specify something else to get
everything in one swoop that i might ever need

thanks
