I haven't seen a response to this on the list.
OpenSSL does not include a collection of trusted certificates. You need to get them from some other source. You may copy them from your OS distribution, for example.
Another popular source is the Mozilla certificate collection. Adam Langley wrote a Go program that converts the Mozilla collection to PEM and excludes those marked as untrusted; you can find it at:
(And Go itself is available from https://golang.org, of course, if you don't have that installed.)
There are many opinions about what constitutes a good collection of trust anchors for various applications. Some people feel the collections provided with most OS and browser distributions are too generous, and saccrifice security for interoperability. If you're going to assemble a set of trust anchors that includes public CAs, it may be a good idea to familiarize yourself with the issues. Ivan Ristic's /Bulletproof SSL and TLS/ (available at https://feistyduck.com) has a good survey.
