Frankly I wouldn't be surprised if snapshots are dodgy, to be quite
honest. As far as I'm aware, most people just build GHC HEAD
themselves, from the git repository. And a snapshot build does not
necessarily guarantee anything works in any case (there could be a
million things wrong in the repository causing failures in a binary
distribution you might not see in a developer build.)
So, if you want to build GHC, you can. This can be done in well under
an hour (or even 30 minutes) with a moderately powerful machine and
paying attention to build settings.
Check out the first section, 'Building GHC', here
And this page which has some good tricks for speeding up the build,
like using 'mk/build.mk':
