A modern version of Inkscape would be nice.
From a quick search at the compiling instructions and nekoware it seems that the requirements are here...
Doing a further search on Inkscape 0.45 Release Notes i found the below:
Thanks to patches submitted by users of our community, Inkscape can now be built on SGI IRIX 6.5.28, gcc 3.4.0 systems and on Tru64 systems.
Anyone can help on this. Is there a binary around?
