[LRUG] Ruby 2.4.1 openssl install error

[gvim]

A few weeks ago I installed 2.4.0 painlessly with rbenv on OS X Sierra. 
Yesterday I tried installing 2.4.1 on 2 OS X Sierra machines and after 
the initial openssl download completed and the Ruby install was about to 
complete I received this error:

Installing ruby-2.4.1...

Earlier in the install log I found:

../.././ext/openssl/extconf.rb:64: Ignore OpenSSL broken by Apple.
../.././ext/openssl/extconf.rb:64: Please use another openssl. (e.g. 
using `configure --with-openssl-dir=/path/to/openssl')

But openssl was downloaded at the beginning. WTF?
