Enough folks on the MySQL mailing list have asked for 4.1 builds, that I'm providing them for Linux. They're unsupported. They're untested. I build them when the spirit moves me. I may build them nightly if there's demand. I've already automated the process, but I still kick if off by hand. (I've been doing this for ages, but I never made 'em available.)
You'll find them at: http://jeremy.zawodny.com/mysql/builds/
The filenames should be pretty clear. Note that "cow" is the machine on which they're built. It's a Debian "testing" box. The binaries are configured to be unpacked in /home/mysql and run from there. That way they don't get in the way of your vendor-provided install.
Have fun.
Oh, if you want FreeBSD builds, let me know. I've got those automated too.
According to Russell:
ANY company/person who wants to ignore M$ is being stupid.
I'm being stupid. It's not that I want to ignore them, I simply do.
Ya know what? I'm fine with that. I really don't care what they're up to. Microsoft is largely irrelevant for me.
