i don't know how to fix the above problem, without having a linux 
machine myself.  if you have a patch for this, open a PR.

I have a fair idea on how to fix this.  but it isn't pretty.  the nss 
build system is really unpleasant and I doubt nss even compiles on 
FreeBSD with pkgsrc (although I have not had a bug report about it).

so if you take the first problem, i'll take the second.  i'm in the 
middle of writing my thesis at the moment, so it will be a day before i 
get the time to sort this.
