Was seeing the ‘sed’ issue on Mac OS X Sierra (10.12.6). Had homebrew installed so:

% which sed
/usr/local/bin/sed

The simple fix was to temporarily move homebrew sed out of the way:

% cd /usr/local/bin
% mv sed sed0

Now sed reports using the stock one:

% which sed
/usr/bin/sed

Ran the installer. This time it ran to completion. Then renamed sed back to where it was:

% cd /usr/local/bin
% mv sed0 sed

Thanks for the tip.
