`cannot find -lreadline'

[S.D.Mechveliani]

Dear  ghc-5.02.2  (linux-i386-unknown, binary snapshot for libc-2.1),

For the program         main = putStr $ show $ (2+3 :: Int)

                        ghc --make Main
`makes' it all right.
And                     ghci -package docon Main
also works.
docon  is my user package, with  .hi files, .o, .a  libraries 
gathered in certain directory. 

And                     ghc -package docon --make Main
yields
        ghc-5.02.2: chasing modules from: Main
        Skipping  Main             ( Main.hs, ./Main.o )
        ghc: linking ...
        /usr/bin/ld: cannot find -lreadline
        collect2: ld returned 1 exit status

How to fix this thing?
Does this error refer to  libreadline.so.3  ?
When installing binary ghc, I made a link for  libreadline.so.3.
