Pointyhat uncovered a problem with devel/lamson where a reinstall followed by a deinstall would leave residue. The same underlying error is in the devel/py-daemon port. The attached patch fixes the bug. Fix: Patch attached with submission follows:
Responsible Changed From-To: freebsd-bugs->amdmi3 I'll take it.
State Changed From-To: open->closed Committed. Thanks!
