Evernote API PHP示例不适用于Ubuntu12.04

当尝试位于示例/客户端中的EDAMTest.php文件时，我得到以下错误：

$ php EDAMTest.php 
Uncaught TTransportException:
exception 'TTransportException' with message 'THttpClient: Could not connect to sandbox.evernote.com:443/edam/user' in /home/mike/evernote/lib/transport/THttpClient.php:196
Stack trace:
#0 /home/mike/evernote/lib/packages/UserStore/UserStore.php(57): THttpClient->flush()
#1 /home/mike/evernote/lib/packages/UserStore/UserStore.php(37): EDAM'UserStore'UserStoreClient->send_checkVersion('Evernote EDAMTe...', 1, 22)
#2 /home/mike/evernote/sample/client/EDAMTest.php(78): EDAM'UserStore'UserStoreClient->checkVersion('Evernote EDAMTe...', 1, 22)

尝试从浏览器（通过apache）运行它也会失败。

当谷歌搜索时，似乎是openssl问题，安装了openssl：

$ openssl version
OpenSSL 1.0.1c 10 May 2012

它也被启用为apache mod:

$ ls -la /etc/apache2/mods-enabled/
(...)
lrwxrwxrwx 1 root root   36 Sep 11 19:57 ssl.conf -> /etc/apache2/mods-available/ssl.conf
lrwxrwxrwx 1 root root   36 Sep 11 19:57 ssl.load -> /etc/apache2/mods-available/ssl.load
(...)

我可能做错了什么？
