modified-bsd license?

[John Klos <john%ziaspace.com@localhost>]

Hi, all,

I'm now thoroughly confused. Now it is MANDATORY for people to have 
ACCEPTABLE_LICENSES+=modified-bsd in /etc/mk.conf in order to use pkgsrc?

ERROR: This package has set PKG_FAIL_REASON:
ERROR: pkg_install-20090528 has an unacceptable license: modified-bsd.
ERROR:     To view the license, enter "/usr/bin/make show-license".
ERROR:     To indicate acceptance, add this line to /etc/mk.conf:
ERROR:     ACCEPTABLE_LICENSES+=modified-bsd

What the hell? Who thought it was a good idea to do this?
