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.
Can you tell us exactly which versions of GHC and Cabal you were using
when the build failed? We should be able to reproduce the problem from
that.

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.

I don't know what might case this I'm afraid. Is it reproducible
from a completely clean tree? (i.e. make maintainer-clean first).
