I saw this same error, building GHC 7.0.2 from source on OS X.
My builds are completely scripted, so I could attempt any experiments that would help. I always expect issues with major (here, 6 => 7) version changes; here all issues surrounded cabal-install in one way or another.
My issues went away when I compiled GHC 7.0.2 using a bootstrap copy of GHC 7.0.2 (rather than from GHC 6.12.3). made the new install the active GHC, and then ran ./bootstrap.sh --global to install cabal-install-0.10.2. Either the change from cabal-install-0.10.0 helped (I couldn't track down release notes) or there is a subtle difference in a GHC 7.0.2 compiled from GHC 6.12.3, that gets exposed when one tries to install cabal-install.
I still can't use cabal-install on one copy of 7.0.2 to install to another copy of 7.0.2, but it looks like something I'll manage to sort out without help.
I use PREFIX to localize the installation to e.g. /usr/local/ghc-7.0.2c. This requires that my script edits bootstrap.sh, as there's no way to change PREFIX from outside in --global mode.
