+	* ext/openssl/ossl_pkey_ec.c: Ensure compatibility to builds of
+	  OpenSSL with OPENSSL_NO_EC2M defined, but OPENSSL_NO_EC not
+	  defined.
+	* test/openssl/test_pkey_ec.rb: Iterate over built-in curves
+	  (and assert their non-emptiness!) instead of hard-coding them, as
+	  this may cause problems with respect to the different availability
+	  of individual curves in individual OpenSSL builds.
+	  [ruby-core:54881] [Bug #8384]
+
+	  Thanks to Vit Ondruch for providing the patch!

3. Create “fedora.configure” file
4. Copy the content below.

#!/bin/sh
patch -p0 -i /tmp/patch.diff
exec ./configure "$@"

5. Execute this command.

RUBY_CONFIGURE=/home/user/fedora-configure rbenv install 2.0.0-p247

6. check ruby version.

rbenv versions
