Purposed patch: https://reviews.freebsd.org/D23424 security/nss installs header and lib files to ${PREFIX}/include/nss/nss and ${PREFIX}/include/nss which add some difficulty of porting some softwares. For example, recently I got some path issues when updating security/xmlsec1 Also the extra 'nss' in the path seems not very useful.
