Compiling R on CentOS

What's the problem with the CentOS I'm working with... seems so many necessary components are missing from regular Linux distro I have been working with>_<

During configuration, following errors tell that F77 compiler is missing, and I installed following:
# yum install compat-gcc-34-g77.x86_64

And re-config, again error complains that readline utility is missing.
After yum search readline, I chose to install this:

yum install readline.x86_64

but did not work. then I installed this:

yum install readline-devel.x86_64

and it worked!

Go on to install bioconductor:

> source("http://bioconductor.org/biocLite.R")
> biocLite()

Everything OK.
