At do_package time I can't modify the variables RDEPENDS, RRECOMMENDS
and RSUGGESTS as stated in the following email:
http://lists.openembedded.org/pipermail/bitbake-devel/2013-April/003416
.html
I've tried the smallest changes to these 3 fields but without success,
confirming what was said in the email.
I do manage to get the auto pr data (Version=4.1+git168+a7e53ecc27-
r0.73 - notice r0.73) that I need to version the dependencies.

At variable loading time I could globally change RDEPENDS, RRECOMMENDS
and RSUGGESTS but I can't get the auto pr data. Since I have no auto pr
data, I can go as far as getting Version=4.1+gitAUTOINC+a7e53ecc27-r0
(notice r0, not r0.73) which is incomplete.

The only place I've actually managed to insert the data was at package
creation time (ipk, deb, rpm), which I agree is ugly but I've not found
another to get me where I need.

Thanks for the feedback,
Ovidiu
