Final Success: The “Clean Slate” Method
If MAKE_JOBS_UNSAFE doesn’t resolve the build failure, you may be facing a conflict between the new source code and a stale version of the package already installed on your system.
The “Nuclear” Workflow
When the build system gets confused by existing libraries, the most effective fix is to remove the existing package entirely before attempting a recompile:
# 1. Remove the existing GStreamer plugins
pkg delete -f gstreamer1-plugins
pkg delete -f gstreamer1-plugins
# 2. Clean the ports tree work directory
make clean
# 3. Rebuild and install from scratch
make install clean
Why this works: Compilers sometimes favor libraries in
/usr/local/lib over the newly compiled versions in the temporary build folder. By deleting the old package, you remove the possibility of a version mismatch or “linker confusion” during the build process.
