The installer can't create the links to your /usr/local/bin folder anymore under El Capitan.
How come? The /usr/local hierarchy is expressly excempt from the restrictions that apply to the rest of the /usr hierarchy. I have all kinds of stuff in /usr/local myself, no trouble at all. But Haskell platform used to install binaries in /usr/bin, which is definitely a no-no on El Capitan. I think a workaround was posted to this mailing list, or was it on cafe? Personally, I have abandoned Haskell platform in favour of the installation instructions here: https://github.com/bitemyapp/learnhaskell/blob/master/install.md So I couldn't comment on the viability of the workaround that I saw. – Harald PS. I don't know what happens if /usr/local did not exist when you installed El Capitan. Is it then necessary to turn off SIP in order to create this directory, due to the restrictions on /usr?
