Cabal fails to reinstall base or any other dependencies in sandbox Cabal

EDIT FURTHER SHOWERS THAT ARE ON THIS:

It would be unwise to copy any of my commands below, not to execute them. Just check Zeta's answer, why I was approaching this wrong.

ORIGINAL QUESTION

My sandbox seems to fall into the global version of some packages, rather than using versions for the sandbox. I looked at SO for answers to this, and many of the questions are answered without specific instructions on how to fix this, or were slightly different, so I cannot get my installation to work. Here is what I have:

1. Version of cabal is old:

$ cabal --v
cabal-install version 1.16.0.2
using version 1.16.0 of the Cabal library

Oh dear, this is old and will not run the sandbox.

2. Install cabal with cabal
$ cabal install cabal
Resolving dependencies...
Downloading Cabal-1.22.6.0...

...lots of stuf...

Registering Cabal-1.22.6.0...
Installed Cabal-1.22.6.0

Looks good.

3. Try it out:
$ cabal sandbox init
cabal: unrecognised command: sandbox (try --help)

Hm.

$ which cabal
/usr/bin/cabal

Ahh.

$ ${HOME}/.cabal/bin/cabal --version
cabal-install version 1.22.2.0
using version 1.22.2.0 of the Cabal library

Yeah.

$ export PATH="${HOME}/.cabal/bin/:$PATH"
$ export PATH="${HOME}/.cabal/libs/:$PATH"

$ cabal --v
cabal-install version 1.22.2.0

Great.

4. Try it out again:
$ cabal sandbox init
Writing a default package environment file to
.../cabal.sandbox.config
Creating a new sandbox at .../.cabal-sandbox

$ cabal install Frames

Yes, the base is not compatible, OK.

What about all the dependencies?
