install issue on RHEL 5

[dave.stauffer]

Thought I had all the dependencies but I am getting this error on RHEL
5 x86_64 system when I run 'scons install'

<snip>
./configure --prefix="/opt/cast/node"
Checking for program g++ or c++ : not found
Checking for program icpc : not found
Checking for program c++ : not found
/tmp/cast-0.2.0/build/node/wscript:232: error: could not configure a
cxx compiler!

Did a little google search and found some people installing 'build-
essentials' on ubuntu to get node.js running.

I didn't see that package in the install notes so I was wondering if I
was on the correct path to solving the problem or not?

Thanks

Dave
