pkg-static segfaults when a port makes a package in chroot/nanobsd.

I have a ticket open in github for this, but I wanted to mail in and let 
people know that I figured the problem out somewhat:

Thanks everyone!  For what it's worth my ports tree's latest commit is this:

commit e6fcb0faa8aeb5905bad5c295f319917aafd21ff

     misc/py-qt4-demo:
     - Use plist instead of PORTEXAMPLES, otherwise the package is bogus 
when
       NOPORTEXAMPLES is set
     - Use compileall.py to byte-compile installed examples
     - Use options helpers
