Really cross-compiling is pretty hard. See /usr/pkgsrc/doc/*cross*. But, I can suggest two things that will help and are less hard. 1) Set up ccache, with a big enough cache size. See the guide, but I have in mk.conf: PKGSRC_COMPILER= ccache gcc CCACHE_DIR= /home/gdt/.ccache 2) Use distcc and on the remote machine run the NetBSD toolchain that you built cross with buidl.sh. Still do the build on the Qube, but have it use distcc to outsource the actual compiling. This is vastly easier because the build process for each package will not perceive that anything is cross. You'll have to do some hackery to get a distcc call that wants "gcc" to really get the cross version from the TOOLDIR, but that's way easier than actually making cross-compiling work right. And it should just be fiddly, not truly hard. I have not done this, just thought about it. If you do figure out a nice way, it would be great to document it for others.
