title: How do I update libcurl to 7.21.7 when I've updated the command line curl OSX?
body: <p>I've built curl and copied the binary and /.libs over to /usr/bin. The command now gives:</p>
  
  <pre><code>curl 7.21.7 (x86_64-apple-darwin10.8.0) libcurl/7.21.7 OpenSSL/0.9.8k zlib/1.2.3
  Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smtp smtps telnet tftp 
  Features: IPv6 Largefile NTLM SSL libz 
  </code></pre>
  
  <p>Yet curl_version() gives:</p>
  
  <pre><code>libcurl/7.19.7 OpenSSL/0.9.8r zlib/1.2.3
  </code></pre>
  
  <p>How do I update libcurl as well on OSX 10.6.8?</p>
  
  <p>Thank you.</p>
  
  <p>I also have these files under /usr/bin:</p>
  
  <pre><code>/usr/lib/libcurl.2.dylib
  /usr/lib/libcurl.3.dylib
  /usr/lib/libcurl.4.dylib
  /usr/lib/libcurl.dylib
  </code></pre>
  
  <p>Do I have to compile another one of these? I don't know how, with what, where. I also have these:</p>
  
  <pre><code>/Developer/SDKs/MacOSX10.5.sdk/usr/lib/libcurl.2.dylib
