AC-Vector is a simple (single source) package only requiring the base
package, so even without "cabal-install" (that installs the "cabal"
binary) you should be able to download and unpack it:
ghc --make Setup.hs
./Setup install --user

I wonder which "cabal" binary was used? (from an old installation?)

So a new binary was installed in /home/jdh30/.cabal/bin. Check if
cabal-install version 0.8.0
using version 184.108.40.206 of the Cabal library
and replace your older cabal version (in your PATH).
If you still see an older version (of the Cabal library) you may need to
bootstrap cabal-install-0.8.0 and manually install parsec-220.127.116.11 and
network (i.e. version 18.104.22.168) before (as described above for AC-Vector).
P.S. If you add "--global" to "cabal install" binaries will be installed
under /usr/local/bin (and libraries in the global package.conf file)
