Pythonを2.7.10にアップデートしたら、py2exeでパッケージングしたEXEで以下のエラー。対処方法のメモを残しておく。

ImportError: cannot import name RAND_egd

py2exeはとてもありがたいのだが、この手のエラーが多いのが困る。

暫定的な対応だがsocket.pyでRAND_egdをimportしているところをコメントアウトしたらエラーが解消された。

    # we need to import the same constants we used to...
    from _ssl import SSLError as sslerror
    from _ssl import \
         RAND_add, \
         RAND_status, \
         SSL_ERROR_ZERO_RETURN, \
         SSL_ERROR_WANT_READ, \
         SSL_ERROR_WANT_WRITE, \
