Compiling nmap on Red Hat

[Francois Lachance <digitallachance () gmail com>]

I am trying to compile nmap 6.0 (fresh download of source) and I seem to be
missing something on my system.

The error message is:

As you can see, I did not have make available, so I tried gmake instead.
 That seemed to work until it tried to use g++, which appears to be missing
on my system.  I cannot for the life of me figure out how to install g++.

Anyone ever ran into this?  I have not found any postings with this problem
in this list and Google is less than helpful.

My system is Red Hat Enterprise Linux Client release 5.8 (Tikanga).

Thanks,

Francois
