I'm familiar with building DMD/Phobos on linux32/64 (and I assume freebsd is much the same, aside from having to install GNU make), but I know OSX is different in that the 32/64-bits bins are combined. I don't have access to a modern OSX machine ATM, but I might have a little bit of time with one tomorrow (I'm pretty sure it's either 10.6 or 10.7 - I know it's a Core i7 laptop FWIW).
So I wanted to ask, is there anything I should know about doing a full build of DMD/Phobos on OSX? Is it just like doing a 32-bit-only or 64-bit-only build on linux, but just without using -m32/-m64? Or do I do one arch and then the other? Or does it differ between the different components (dmd/druntime/phobos)? Etc. And are there any special OSX-only prerequisites?
