Dave, thanks for the info
for what it's worth, it is generally a bad idea to --with-xxx=/usr since you might inadvertently use some other external components. in your case, --with-libevent=external is what you need if you want to use an external libevent library installed in /usr i guess the same comment would apply with /usr/local too btw, which distro are you using ? is your distro's libevent up to date ? we might want to add a FAQ entry with a known to be broken libevent Cheers, Gilles On Sun, Dec 18, 2016 at 10:52 AM, Dave Turner <drdavetur...@gmail.com> wrote: > > I've solved this problem by omitting --with-libevent=/usr from > the configuration to force it to use the internal version.
