I attempted to put it together with cc and discovered that i have no compiler application on my production box. Google mentioned GCC, which I found the correct RPM's (including dependencies) for, and I was able to install most of then until I realized that I have a quandry:

[root@dev21 /home/dev/gcc] rpm -Uvh gcc-4.6.3-2.aix5.2.ppc.rpm
error: failed dependencies:gcc-cpp = 4.6.3-2 is needed by gcc-4.6.3-2

[root@dev21 /home/dev/gcc] rpm -Uvh gcc-cpp-4.6.3-2.aix5.2.ppc.rpm
error: failed dependencies: gcc = 4.6.3-2 is needed by gcc-cpp-4.6.3-2

A needs B needs A

Please explain this to me. Can i use the --nodeps flag?

I'm at a loss at this point. Any help would be appreciated.
No, you can not use the --nodeps flag it you want it to work. Each rpm has its own dependency and it is necessary for that dependency to be met.
If you want to do it manually (which is what you are doing), you must know the dependencies of each package and issue the rpm command with each one in daisy chain. That is:
Code:
rpm -Uvh one.rpm two.rpm three.rpm ...

Now, there is a tool that automatically checks for each dependency required and it will try to download it from the configured distribution repository.
This tool is yum for RHEL and clones of it, and Fedora <= 21.
Fedora >= 22 had yum replaced by DNF.
Suse uses zypper.

The basic command for yum:
Code:
yum install gcc

NAME
rpmspec - RPM Spec Tool SYNOPSIS
QUERYING SPEC FILES: rpmspec {-q|--query} [select-options] [query-options] SPEC_FILE ... select-options [--rpms] [--srpms] query-options [--qf,--queryformat QUERYFMT] [--target TARGET_PLATFORM] QUERY OPTIONS The general form of an rpm spec query command is rpm {-q|--query} [select-options] [query-options] You may specify the format that the information should be printed in. To do this, you use the --qf|--queryformat QUERYFMT option, followed by the QUERYFMT format string. See rpm(8) for details. SELECT OPTIONS --rpms Operate on the binary package header(s). --srpm Operate on the source package header(s). SEE ALSO
popt(3), rpm(8), rpmdb(8), rpmkeys(8), rpmsign(8), rpm2cpio(8), rpmbuild(8), rpmspec --help - as rpm supports customizing the options via popt aliases it's impossible to guarantee that what's described in the manual matches what's available. http://www.rpm.org/ <URL:http://www.rpm.org/> AUTHORS
