 Note that Julia is community-supported and we have little control over our upstream dependencies, you may still run into issues with dependencies and YMMV. Current known issues include:
 
  - The x86 arch doesn't support threading due to lack of compiler runtime library support (set `JULIA_THREADS=0`).
- - libunwind needs a small patch to its tests to compile.
  - OpenBLAS patches in pkg haven't been upstreamed.
  - gfortran can't link binaries. Set `FFLAGS=-Wl,-rpath,/usr/local/lib/gcc6` to work around this (upstream bug submitted to FreeBSD pkg maintainers).
  - System libraries installed by pkg are not on the compiler path by default. You may need to add `LDFLAGS=-L/usr/local/lib` and `CPPFLAGS=-I/usr/local/include` to your environment or `Make.user` file to build successfully.
