Hi,
I wanted to try this under Windows also, but there are even more 
problems, since "pcre-light" dependency is not available (perhaps in 
case of using MSys, MingW)
Hartmut

Windows, cabal 1.16.0.2, I got

cabal install rex --dry-run

    Resolving dependencies...
    In order, the following would be installed (use -v for more details):
    hslogger-1.2.1
    MissingH-1.2.0.0
    pcre-light-0.4
    split-0.2.1.1
    th-lift-0.5.5
    th-orphans-0.6
    haskell-src-meta-0.6.0.1
    rex-0.3.1

cabal install

    Resolving dependencies...
    Configuring pcre-light-0.4...
    cabal: Missing dependency on a foreign library:
    * *Missing C library: pcre*
    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: Error: some packages failed to install:
    pcre-light-0.4 failed during the configure step. The exception was:
    ExitFailure 1
    rex-0.3.1 depends on pcre-light-0.4 which failed to install.
