[erlang-questions] Erlang Crypto R16+ and Centos 6.4+ incompatibility

It happened because he built with an OpenSSL which doesn’t incorporate Red Hat's errata, most likely. This was an issue with a great many products for all of like a week or two while the broken packages were being delivered.
It's not Erlang's fault. And Red Hat fixed their packages. The only two likely options are that the distro (or, more likely, system) does not have the current packages; or, there is a new bug which needs to be filed with Red Hat (less likely).

configure has nothing to do with it. When openssl is configured and build
a file named opensslconf.h is generated (on Ubuntu it's installed to
That file is indirectly included though the other openssl headers and
specifies at compile time what ciphers are supported. That your Erlang
was compiled with EC support when your openssl seems to be missing
support for it, means that that config header must be broken.
Would be great to know how that happened.
