I experienced this issue with cuse4bsd-kmod and Virtualbox kernel modules. See ports/151603 for example. >How-To-Repeat: 1) Set your $PATH the way thet /usr/local/bin is the first entry in it: export PATH=/usr/local/bin:$PATH 2) Install virtualbox-ose with virtualbox-ose-kmod from ports. 3) Try to load the kernel module vboxdrv.ko 4) You'll see messages on undefined symbols 5) Try to build, install and them load cuse4bsd.ko from ports - it won't create any proper /dev/cuse devices expected from this kernel module >Fix: 1) Deinstall devel/binutils before building kernel modules or 2) Change $PATH so that system binutils are found, not the ones from the port The actually fixed situation should either allow to build _usable_ kernel modules with any binutils in use, or automatically detect the correct ones, or at least warn a user about possible issues. >Release-Note: >Audit-Trail: >Unformatted:
