Curl broken in OSX?

Wasted two hours today attempting to HTTP POST some content with a client certificate using curl on OSX Snow Leopard. It somehow would not show its cert to the Apache server.

In an act of desparation, I tried the exact same command with the exact same client certificate on Linux, and it worked.
