and via FTP. For more information, see:
http://www.feyrer.de/NetBSD/wildcards.html
Un-munge pkg_install/lib/Makefile which I'd overwritten on libftpio commit.
Make it compile on NetBSD.
Install pkg_* programs in /usr/sbin
XXX agc - Still to do XXX
Cleanup call to mktemp (for a tmp dir) in pkg_install/lib/pen.c
Create ftperr.c in the correct directory.
