OpenSSL::BN#prime?を引数なしで呼ぶと以下の通り例外が出ます。

irb(main):001:0> require'openssl'=> trueirb(main):002:0> OpenSSL::BN.new("461166461445805738999").prime?
TypeError: no implicit conversion from nil to integer
from (irb):2:in prime?' from (irb):2 from /home/naruse/local/ruby_1_9_2/bin/irb:12:in '

コードを見るに、rb_scan_args の引数との比較が誤っているように見えるので、引数ありでもおかしいでしょう。
以下の変更で直ります。
