It would be really nice to have Apache JMeter available via Portage for those of us doing QA and testing work with Gentoo. More info: http://jakarta.apache.org/jmeter/index.html
sorry, no time :(
If you can contribute with an ebuild, it should be available sooner than wait for a developer to make it.
Eric -- I created this ebuild not aware that you had posted a bug on it. But I caught this afterwards. It's now in the system (masked) as app-benchmarks/jmeter. Please test it out and let me know how it works for you. Post your comments here, or email me. Cheers
