cURL/wget - SSLv3, TLS handshake, CERT hangs

Question

I have problems connecting to https sites using cURL or wget. When I download from a https curl seems to be stuck while doing the TLS handshake, CERT. The problem is independent of the site (I noticed it using github) and wget is hanging too (although I didn't look into the verbose outputs there).

$ curl -v --trace-time https://www.google.de
10:35:21.532822 * About to connect() to www.google.de port 443 (#0)
10:35:21.533091 *   Trying 209.85.148.147... connected
10:35:21.538666 * Connected to www.google.de (209.85.148.147) port 443 (#0)

10:35:21.544129 * SSLv3, TLS handshake, Server hello (2):
10:35:21.544182 * SSLv3, TLS handshake, CERT (11):

I have waited >10 min but nothing happens. I am using OSX Lion.

$curl --version
curl 7.21.4 (universal-apple-darwin11.0) libcurl/7.21.4 OpenSSL/0.9.8r zlib/1.2.5
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smtp smtps telnet tftp 
Features: AsynchDNS GSS-Negotiate IPv6 Largefile NTLM SSL libz

I don't know where to look for help so I'd be happy if you could give me some pointers.

Thanks

It seems you are not able to verify the certificate since you are missing the ca-bundle.crt. This belongs (in CentOS 5) to the openssl-rpm.

A good way to manage these things in Mac OS X / Darwin would be to install a packagemanager such as Homebrew (http://brew.sh/)

This way when you install software like cURL you would get the whole dependency list too or you can just brew install openssl and problem solved ;)
