The other problem is that I can't figure out the location of the build
directory. The program ask you to check config.log, which seems like
a very reasonable thing to do, but I can't find it anywhere.
Anywhere, being in .cabal.
Is the build dir being removed on failure ?

uh, that doesn't work :-(
$ cabal configure --configure-option=--extra-include-dirs=/sw/include
cabal: No cabal file found.
Please create a package description file <pkgname>.cabal
However, I understood what you were trying to do, and figured out the
following command, which _did_ work !
cabal install readline --extra-include-dirs=/sw/include --configure-
I'm not sure if the --extra-include-dirs is needed, it seem like maybe
just the --configure-option flags would have been enough.
Now if only I could remember what I was trying to install when
readline failed to install :-)

Why should they behave better ??
Cabal really needs some additional debugging flags of some sort. It's
fairly painful to figure out the problem if it fails.
