ghc: build fails with permission denied on symlink creation

[cdeil (Christoph Deil)]

I got this error trying to install ghc on Mac OS X 10.8:

That doesn't appear to be relevant, and that's not what's in the log you attached. But I'm unfamiliar with the ghc build system and I'm having a little trouble figuring out from the attached log what the relevant error is.

I simply copy & pasted the output on my console and attached the log.

I'm not familiar with ghc either, all I want is to install pandoc, which is a dependency for nbconvert (​https://github.com/ipython/nbconvert), a python tool I want to use. hs-platform-ghc did install for me without problems and seems to contain the same thing as the ghc port. Unfortunately pandoc can't be built with hs-platfrom-ghc apparently:

$ sudo port install pandoc

During a Macports update I saw this:

Is it relevant? Should I simply try uninstalling and re-installing ghc-bootstrap and ghc?

Please clean ghc and re-try. If the issue persists, please attach main.log.

Yes, this is unfortunate, and I'm currently thinking of a solution for this problem.

See #36996.

OK, I did this:

sudo port uninstall --follow-dependents hs-platform-ghc
sudo port clean --all ghc
sudo port install ghc
sudo port install pandoc

Installing ghc now worked without problems, but trying to install pandoc I ran into this error with the hs-pandoc-types port:

...

That's #36608. Your previous problem probably was a permission issue in your ports tree.
