Build of OpenConnect 7.05+ for EL6?

I'd be happy to help test this.

I'm very new to building C/C++ on Linux, so please bear with me.

I've installed the scratch builds of libp11 for EL6 you posted David,
both the release and devel packages.  I've also installed the
p11-kit-devel package, and verified I have p11-kit installed.

Right now I'm stuck on the configure step of building OpenConnect.
Now, I'm building src rpm from the link you posted Nikos with the EL6
release of OpenConnect, if that makes a difference.  I'm getting
warnings that my version of GnuTLS is too old, and that my version of
OpenSSL is known to be broken with Cisco DTLS.  I'm running RHEL6
configured to use a local repo on our corporate network, and there are
no updates to either of these packages.  Am I required to have to find
updated versions of one of these packages to proceed?
