I think that it is simpler than you think.  Cabal is confusing you.

Well, the Makefile is just sugar for the Cabal Setup.hs file.

Running --configure notices that many things are not installed, but this is just
noise from Cabal.

With my development directory I get this output from "./setup --configure":

This is sufficient to compile regex-pcre so long as you also have libpcre where
ghc will find it.  The main this is that it found ghc-6.6 and the hsc2hs and
ghc-pkg that came with ghc.

Specifically commands to run:

make setup  # this means Setup.hs is compiled once into "setup" for speed
./setup --configure -p --user --prefix=/where/you/want/it
./setup build
./setup install --user
./setup clean

If you really want it to be global, then remove the --user and --prefix and
install with sudo.

Also, "./setup --help" is useful.
