You mean to run:

cabal install parameterized-data

"cabal configure" expects to be run inside the build tree. It's looking
for a Setup.hs in the current directory. The configure command is for
developers working with their own packages locally, rather than for
working with released packages directly from hackage.

There are basically two sets of commands, those for working with
released packages by name, and those for working with a local package in
the current directory. I'll tried to make that clearer in the
cabal-install README, and perhaps in the --help output in future.
