MNT_NODEV mount option has been removed from -CURRENT (version 700008). Fix: You should apply this fix (or something similar) to the py-freebsd source base, and maybe release a new version of py-freebsd.
Responsible Changed From-To: freebsd-ports-bugs->perky Over to maintainer.
State Changed From-To: open->closed I updated to the new version. Thank you!
