Should be possible, I'll get back to you.

I managed to get 1.4.3 compiled using Fedora CVS, but I don't think the
package is particularly stable. I had zero experience building RPMs
before today, I'm more of a Debian person. It doesn't segfault on
startup though and answers to queries. Upper limit seems to be a little
less than 15000 qps according to resperf, but I haven't fine-tuned the
configuration yet.
