Help; newbie to RPM and troubles with tar!

[Matthew Allen <Matthew Allen red-m com>]

Dear All,

I could use a little help!
This is the first time I have tried to use rpm.

We are putting together a new software package.
We will be shipping the beta release as rpm binary only.
The rpm spec file is trivial but doesn't work!

The target.tgz file is our complete system.

If I install the rpm manually on a preinstalled redhat6.1 system (rpm -i
genosXXXXXXX)
it works fine. The problem comes when we add it to our redhat installation
disk. It installs the target.tgz file and creates the genos-extra dir
correctly but complains in the /tmp/install.log
with the following ;

...
...
Installing libtermcap.
Installing bash.
/var/tmp/rpm-tmp.80120: tar: command not found
user mdallen does not exist - using root
execution of script failed
Installing shadow-utils.
Installing MAKEDEV.
...
...


Al I want the rpm to do is un tar the target and run the internal scripts.
Sounds easy but it currently doesnt work. In fact I cant get any
commands such as cp or mkdir to work in the %post section either.
I must be doing something very wrong.
Can anyone help?

I would appreciate it as we are shipping in a fortnight!

Thanks,
Matt
