These are api warnings from the linker, unfortunately fairly common to trigger them when porting software, they're mostly helpful for people using OpenBSD as a dev platform (and as a bit of a warning to porters that some things might be worse than usual ;) > 3.

It's not ideal but in practice hasn't caused problems. As far as Otter goes I think building with 4.8 would be a good idea, if you're doing this within the ports framework, something like the below in the Makefile will set it up: MODULES += gcc4 MODGCC4_ARCHS = * MODGCC4_LANGS = c++ > Warning: QGtkStyle could not resolve GTK.
