I think I am very atypical as I had the Haskell Platform installed and did an uninstall-hs before installing this release candidate. This is on the latest Mac OS and Xcode.

At the time I got the error the file was a symbolic link, I believe to an existing file:

install: /usr/local/share/man/man1/ghc.1: No such file or directory
make[1]: *** [install_man] Error 71
make: *** [install] Error 2
bash-3.2$  ls -l /usr/local/share/man/man1/ghc.1
lrwxr-xr-x  1 gcolpitts  admin  80 Jun 23 19:44 /usr/local/share/man/man1/ghc.1 -> /Library/Frameworks/GHC.framework/Versions/8.0.1-x86_64/usr/share/man/man1/ghc.1
bash-3.2$  rm /usr/local/share/man/man1/ghc.1

Now after a successful install of the binary and a successful compile from source I have:

ls -l /usr/local/share/man/man1/ghc.1
-rw-r--r--  1 root  admin  58932 Nov 26 09:16 /usr/local/share/man/man1/ghc.1
bash-3.2$ ls -l /Library/Frameworks/GHC.framework/Versions/8.0.1-x86_64/usr/share/man/man1/ghc.1
ls -l /Library/Frameworks/GHC.framework/Versions/8.0.1-x86_64/usr/share/man/man1/ghc.1
-rw-r--r--  1 root  wheel  58214 May 21  2016 /Library/Frameworks/GHC.framework/Versions/8.0.1-x86_64/usr/share/man/man1/ghc.1

After the binary install I did a cabal install of threadscope, hlint and criterion and some minimal runtime testing. Everything looks fine. 

Thanks
George

Thanks for the report, George! That is quite odd indeed. It sounds like
/usr/local/share/man/man1/ghc.1 may have been a symlink to a directory
which does not exist (possibly?). What does `ls -l
/usr/local/share/man/man1/ghc.1` say now?

Cheers,
