is there a single command to get *ALL* the DEVEL stuff meaning compilers and libs and whatever on the box in "one fell swoop"
yum groupinstall 'Development Tools' will give you everything in this group. It's possible that you may still have to install the odd -devel package depending on what you build, but it'll get you 99% of the way there.
It's amazing what 30 seconds with the yum documentation will give you.....
