Mon, 04 Nov 2013 18:21:02 -0300

On FreeBSD 9, the Port security/openvpn-auth-ldap is flagged as BROKEN because of the following error in the configure build step.

configure: WARNING: Check library not found. Unit tests will not be built or run.
checking for openvpn-plugin.h... no
configure: error: Could not locate a working openvpn source tree.
See `config.log' for more details.
===> Script "configure" failed unexpectedly.
Please report the problem to snb@FreeBSD.org [maintainer] and attach the
"/usr/ports/security/openvpn-auth-ldap/work/auth-ldap-2.0.3/config.log"
including the output of the failure of your make command. Also, it might be
a good idea to provide an overview of all packages installed on your system
(e.g. a /usr/sbin/pkg_info -Ea).
*** Error code 1

Looking at the config.log, we have:
