 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

   Reason: image not found

 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...
