Merge lp:~trond-norbye/drizzle/dtrace-macosx-support into lp:~drizzle-trunk/drizzle/development

[Trond Norbye]

[Trond Norbye (trond-norbye)]

Hi,

I couldn't resist to test this today and I noticed that it was so simple that I thought I should send you a patch :-)

With this patch you can add --enable-dtrace on Mac OSX as well :-)

Cheers,

Trond

Cool, looks good to me! Should I merge this in to my branch or will I just let Monty or Jay pull it in one of their captain branches?

It was for your branch... I had written something wrong in the text
field so it complained to me and when I then resubmitted the field it
had toggled it back to lp:drizzle instead of just you :(

Cheers

[Padraig O'Sullivan (posulliv)]

I'll merge it in to my branch and re-submit my branch.

Thanks again,
Padraig

+  - all *-done probes should have a status argument wherever applicable to make
