security/py-xmlsec has several problems: 1) on build - had to add: CONFIGURE_ARGS+= --with-nss=/usr/local --with-nspr=/usr/local to make it build. 2) on first attempt to import with python: Fix: Not known. Please consult maintainer (ports@freebsd.org) How-To-Repeat: See full description.
Responsible Changed From-To: freebsd-ports-bugs->vsevolod I'll try to solve this problem.
I do not understand why adding such CONFIGURE_ARGS is needed as this port builds successfully without it. About problem with importing undefined symbol: you should update your libxml2 library (textproc/libxml2).
State Changed From-To: open->closed Python related part has been committed.
