sizo_t seems like a very basic thing so im not sure whats happening here

A quick google reveals this breakage is expected with gcc 4.6.0:

Hi Joakim,

Thanks for reporting this. The bug is already fixed in Inkscape trunk. Please see bug #707205 for a patch.

[[e-mail] (joakim-verona)]

But I cant build from trunk still!

I added #include <stddef.h> to utils.h. There didnt seem to be anything like that in Trunk.
Now I get:

[Alex Valavanis (valavanisalex)]

Yes, I had the same problem (comments #12 onwards in bug #707205). I have asked the upstream developers to consider adding #include <cstddef> to src/2geom/utils.h

[Alex Valavanis (valavanisalex)]

...although I believe that 2geom is now maintained externally, so that change may end up being merged into Inkscape trunk at a later date.
