I'd like to install the GHC 7.0.1 RC on my mac (Snow Leopard, x86_64), but I don't want it to run over my current GHC 6.12.2 install.

If I use the .pkg installer, it doesn't allow me to select the destination, and I worry that it will overwrite my 6.12.2 install.

If I try to build from source, that requires me to use my current GHC, which (as I understand) would build for 32 bit.

What other options do I have, or am I misunderstanding something?

Does GHC 7 support 64 bit? For some reason I had thought it was still 32 bit. Antoine
