I tried to replace some of the 32-bit binaries before, but it started to require shared libs as well, so I stopped. I’ll give it a shot later. I now run it with out vnet and it indeed works. I have managed to compile p5-DBD-Oracle which works now. Because all of my other jails were vnet jails, I didn’t think about doing it the old way without vnet.
