I'm not sure about the modifications to the LD vars, though it sounds possible. I regularly test new versions of ports before deploying them. I do this by having a build environment setup in /build. I use chroot to enter the build environment and compile/test the software. I also do this for buildworld when updating the OS. This allows me to install newer (or older) versions of software in the build environment without affecting the running system. > I heard I should use bash and edit the LD_* vars.
