Where you choose to install ghc is not related.

Global always means /usr/local by default, unless you change it in the
cabal config file.

By default ghc, gtk2hs also install globally in /usr/local (unless you
specify a --prefix.)

This tradition of global and /usr/local for ./configure scripts is ok,
but for a convenient package manager it's not necessarily ideal.

Ubuntu/Debian policy seems to be installation into /var/lib/cabal . So it's clear that the whole hierarchy is managed by single tool cabal. Drawback is that you should add /var/lib/cabal/bin into your PATH.
