bug report

Currently, building fails, since pyproj >= v2, needs proj >= v6

ERROR: Complete output from command /usr/local/bin/python /usr/local/lib/python3.5/site-packages/pip/_vendor/pep517/_in_process.py get_requires_for_build_wheel /tmp/tmprpmfab0y:
  ERROR: ERROR: Minimum supported proj version is 6.0.0, installed version is 5.2.0.
  ----------------------------------------
ERROR: Command "/usr/local/bin/python /usr/local/lib/python3.5/site-packages/pip/_vendor/pep517/_in_process.py get_requires_for_build_wheel /tmp/tmprpmfab0y" failed with error code 1 in /tmp/pip-install-vlxcmfol/pyproj

workaround

Freeze pyproj until proj gets updated: pip install [...] pyproj==1.9.6
