[Haskell-cafe] library version problem

Hello,

        I doing work using Linux. The wrong version (for me) of the unix
package seems to be visible. I see possibilities to use ghc-pkg to  suppress
the unix package that I don't want(2.3.0.0) but that seems dangerious.
Details are below .  What should I do?

Regards, vasili



When I do:

> ghci
      :m System.Posix

I am getting the wrong version of the Unix package. I know this to be true
because I did
ghc-pkg latest unix

and got unix-2.3.0.0

I want unix.2.2.0.0 because this version has changes that I made to the unix
package.  libHSunix-2.2.0.0.a is installed under
/usr/local/lib/unix-2.2.0.0/ghc-6.8.2 I did a "nm -a libHSunix-2.2.0.0.a"
and found symbols that I added.
