Hey Keith,

This looks awesome!!
I had a tiny bit of trouble compiling on MacOS X 10.5, here's what I
ended up doing for your benefit or anyone else's...

1. Installed libevent from MacPorts, added
C_INCLUDE_PATH=/opt/local/include
LIBRARY_PATH=/opt/local/lib
to my environment, since I'm using Apple's gcc.

2. That got me as far as a compiler warning from prot.c

cc -O2 -Werror -Wall -c -o prot.o prot.c
cc1: warnings being treated as errors
prot.c: In function ‘h_conn_data’:
prot.c:851: warning: implicit declaration of function ‘writev’
make: *** [prot.o] Error 1

3. I removed the -Wall from CFLAGS in the Makefile, leaving -Werror
and got a clean compile

I was able to go on with the tutorial on the site, but did notice a
small typo. It looks like

beanstalk = Beanstalk::Pool(['10.0.1.5:11300'])

should be

beanstalk = Beanstalk::Pool.new(['10.0.1.5:11300'])

All in all, very cool!

Thanks! This is very helpful.

It will be fixed in the next release.

Fixed.

Thanks so much! I hope you find it useful.

Good job!
Guess it would be much more useful if persist storage could be
provided.

I also had a bit of trouble compiling on Mac OS X 10.4 and CentOS.

Upgrading to Make 3.81 (from 3.80) made it work for me.
