Ok. I did `sudo port hs-cabal` and it went fine. The `cabal` command
is now in `/opt/local/bin`.
Then I did `cabal update`, and I've got a `~/.cabal` dir. Ran `cabal
install haddock` and got:
~~~ snip ~~~
$ cabal install haddock
Resolving dependencies...
No packages to be installed. All the requested packages are already installed.
If you want to reinstall anyway then use the --reinstall flag.
~~~ /snip ~~~
Weird. (How can I check if it's actually installed? Incidentally, it
is not listed in the output of `port installed`, which is:
The following ports are currently installed:
ghc @6.10.3_1+darwin_9_i386 (active)
gmp @4.3.1_0 (active)
hs-cabal @0.6.2_0 (active)
hs-ghc-paths @0.1.0.5_0 (active)
hs-http @4000.0.6_0 (active)
hs-libcabal @1.6.0.3_1 (active)
hs-zlib @0.5.0.0_0 (active)
libedit @20090503-3.0_0 (active)
ncurses @5.7_0 (active)
ncursesw @5.7_0 (active)
perl5.8 @5.8.9_3 (active)
zlib @1.2.3_2 (active)
)
Then tried `cabal install pandoc` and it went ahead and installed it.
(!) I tried it out, and it worked. :)

Good to know. Thanks.
