Failed to load setuid_drv: "Driver compiled with incorrect version of erl_driver.h" when running Yaws

Question

I installed the latest release of Erlang and the lastet Yaws from the master branch. But when I try to run yaws I get an error of `Driver compiled with incorrect version of erl_driver.h". How can I fix this? Doesn't Yaws run on the latest Erlang release? I run this on Mac OS X 10.6.

jonas$ yaws
Erlang R15B01 (erts-5.9.1) [source] [smp:2:2] [async-threads:0] [hipe] [kernel-poll:true]

Update: This answer is no longer meant to be an answer. It's here only to prove its own invalidity.

The latest version of ~~(release version of)~~ Yaws should run happily with the latest Erlang distribution on OSX. ~~Please try downloading the source code of Yaws from http://yaws.hyber.org/download/ rather than from the master branch from GitHub. The master branch of Yaws might be a little bit experimental.~~

The latest release of Yaws (1.92) is very old, and the master branch contains some bugfixes I need. E.g [How do I handle a WebSocket close from the client in Yaws?](http://stackoverflow.com/a/9233292/213269) – Jonas Jun 18 '12 at 08:40
I'm a committer on the Yaws project, and I can say with certainty that the master branch of Yaws is stable and is never intended to be experimental. – Steve Vinoski Jun 18 '12 at 14:00
@SteveVinoski Thanks for your correction. Your comment renders my answer useless. I was about to delete it for the cleanness of SO, but I realized other people may also have the incorrect assumptions as I did, and I decided to keep my useless answer anyway. Thanks again. – Ning Jun 18 '12 at 17:03

I'm successfully running the latest version of Yaws from github master on OS X 10.7.4 under Erlang R15B01 — it definitely works:

Is there any chance you compiled your Yaws sources in the past with a previous version of Erlang (R14Bxx or older), and then tried to build again under R15B01 without first doing a "make clean"? The Erlang driver interface changed between versions 14 and 15, which might explain this error.

I tried to download and compile it again, now it works. I don't know what went wrong last time. Thanks. — Jonas, Jun 18 '12 at 17:18
