ghc-cabal-Random

[Serge D. Mechveliani]

People,

I have  ghc-7.4.0.20111219  made from source and tested it on the 
DoCon-2.12 application -- thanks to people for their help!
It looks all right.
This was -- with skipping the module Random.

Now it remains to add the Random package.
I have taken  AC-Random Version 0.1  from  hackage.
Its installation requires Cabal:   
 > which cabal
 cabal: Command not found.
 >
And Cabal is difficult to install, it reports that such and such package
versions are missing.
On the other hand, Cabal is, probably, present inside ghc-7.4.0.20111219, 
somewhere in the installation directory. Thus I see its  .a and .o files 
in
  ~/ghc/7.4.1pre/inst0/lib/ghc-7.4.0.20111219/Cabal-1.14.0/ 
  
Can you, please, tell me what is the simplest way to install Random in this 
situation?

Thank you in advance for your explanation,
