Unable to install on OSX -- legacy or new-style cabal install?

[GregoryTravis]

I've tried every solution I can find on stackoverflow and elsewhere, and reproduced every installation failure I've seen. In my latest attempts, I'm getting warnings about legacy vs. new-style cabal install commands, and it's unclear to me which one I should be trying to use. Is OSX Haste installation a solved problem, documented elsewhere, or is it no longer supported?

At which point does the build process break, and with what output?

In general, the build process documented here should hopefully work on all platforms. However, since I don't have access to a Mac anymore, tracking down any OSX-specific problems will be difficult. The build instructions were written way before there was a new-style cabal, so when in doubt, use the legacy ones.

@valderman, when I try to cabal install haste-compiler The console log is
