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?

[valderman]

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

`cabal install haste-compiler
