mtl and network packages in GHC 6.10.3.*

[Neil Mitchell]

Hi,

I just downloaded the Windows snapshot of 6.10.3.20090526, and found
that mtl and network don't seem to be included.

$ ghc-pkg list
c:/ghc/ghc-6.10.3.20090526\package.conf:
    Cabal-1.6.0.1, Cabal-1.6.0.3, Win32-2.2.0.0, array-0.2.0.0,
    base-3.0.3.1, base-4.1.0.0, bytestring-0.9.1.4, containers-0.2.0.1,
    directory-1.0.0.3, extensible-exceptions-0.1.1.0, filepath-1.1.0.2,
    (ghc-6.10.3.20090526), ghc-prim-0.1.0.0, haddock-2.4.2,
    haskell98-1.0.1.0, hpc-0.5.0.3, integer-0.1.0.1,
    old-locale-1.0.0.1, old-time-1.0.0.2, packedstring-0.1.0.1,
    pretty-1.0.1.0, process-1.0.1.1, random-1.0.0.1, rts-1.0,
    syb-0.1.0.1, template-haskell-2.3.0.1, time-1.1.2.4

In addition, I can't install network under Cygwin, Mingw, or the
Windows command line. Here are the errors from Cygwin:

Preprocessing library network-2.2.1.2...

And Mingw:

* Missing header file: HsNet.h
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
cabal.exe: Error: some packages failed to install:
network-2.2.1.2 failed during the configure step. The exception was:
exit: ExitFailure 1

And Windows command line:

Resolving dependencies...
Configuring network-2.2.1.2...
cabal: Error: some packages failed to install:
network-2.2.1.2 failed during the configure step. The exception was:
sh: runProcess: does not exist (No such file or directory)

Was removal of these packages on the stable branch was an oversight?
Could network at the very least be reinstated soon? I'd love to report
back whether the GHC 6.10.4 fixes  work or not in practice.

Thanks
