Hi All, I just switched the OpenBSD/powerpc ports (macppc and socppc) over to the "new" Secure-PLT. This improves the W^X support. If you're not following -current closely, you might want to avoid updating from source and install a snapshot instead.
If you decide to update from source, make sure your ld.so is recent (less than two weeks old or so). If not, build a new ld.so first. Then simply do a make build twice to make sure all components are properly switched. Old binaries will continue to work, but will not enjoy the benefits of better W^X. Cheers, Mark
