Ubuntu openoffice sdk

I've tried to make some program for Openoffice calc but there is problem with SDK for it.

As i has previous experience on this SDK on win - i've tried to find sdk for ubuntu on official site openoffice:

http://download.openoffice.org/3.0.0/sdk.html

downloaded it and unzipped
here i found ooobasis3.0-sdk-3.0.1-9366.i586.rpm
WTF? rpm in sh??
tried install it with alien but there was problems of 32 bit (64 bit)
i've spent some time googling it and finally found

with excellent (and very simple) suggestion:

The first thing you need to do is install the OpenOffice SDK. You can get it here, or if you're on Ubuntu you can install it like this:

sudo apt-get install openoffice.org-dev openoffice.org-dev-doc

The doc package is optional, however I find that documentation is a handy thing to have if you need it.

Damn! Why they didn't make link to this on OO site??
And there is really not much info on that in goodle :(

Hope this helps anybody!
