It is very difficult to install the ghc-8.6.1 release candidates (both RC1 and RC2) on MacOS because several components attempt to link directly to /usr/local/opt/gmp/lib/libgmp.10.dylib. This is not a standard path.

See the offending LC_LOAD_DYLIB command here:

The other offenders are libHSbinary and libHSinteger-gmp.

Without changing these load commands, you'll get the following error:

$ ./configure --prefix=...
$ make install
<snip>
dyld: Library not loaded: /usr/local/opt/gmp/lib/libgmp.10.dylib
  Referenced from: ./libraries/base/dist-install/build/libHSbase-4.12.0.0-ghc8.6.0.20180714.dylib
  Reason: image not found
make[1]: *** [install_packages] Abort trap: 6
make: *** [install] Error 2

I tried passing the --with-gmp-libraries option to configure, but that did not help.

I guess this is just a packaging problem, but figured you should be aware before the official release...
