For the typical reasons (older libtool), atk builds only static libraries on Interix. This is easily resolved in the typical way, which if I'm not mistaken is to run eautoreconf instead of elibtoolize. Patch enclosed.
Created attachment 222131 [details, diff] Run eautoreconf on interix
don't overwrite gnome2_src_prepare, ebuilds should use src_prepare only. can you test it this way (a quick build test will suffice): src_prepare() { gnome2_src_prepare || die "gnome2_src_prepare failed" eautoreconf # required for interix } thanks!
interix has no future
