Comment(by lkraider+ports@…):

 Personally I don't have any problems on it depending on python26 only, but
 it should be pointed out that Gramps works with python25, so others might
 find it useful to have that option.

 I broke spelling into a variant since I don't need English spelling
 correction for a family tree app and also prefer to keep dependencies to a
 minimum, but sure, it's not really required.

 Good question about librsvg. I added it because their HowTo page lists it
 as a dependency, I didn't really check the source though: http://www
 .gramps-
 project.org/wiki/index.php?title=Installation#Installing_GRAMPS_from_source_code

 Graphviz is also listed there. I'm not sure it's a build dependency, even
 so, I prefer to have explicit dependencies also for runtime ones, since
 then I can know what a program is able to use feature-wise which I would
 otherwise never find out.
