>Description:

The py27-matplotlib binary package doesn't work; it fails to find
libfreetype.so.7.

My attempted work-around of "pkg_add freetype2" didn't work, either,
because it installed libfreetype.so.6, not libfreetype.so.7.

>How-To-Repeat:

To verify that the problem is not specific to my own pkgsrc setup, I
reproduced it in a fresh 6.1 install as follows:

# pkg_add py27-anita
# anita interact http://ftp.netbsd.org/pub/NetBSD/NetBSD-6.1/i386/
login: root
# export PKG_PATH=ftp://ftp.NetBSD.org/pub/pkgsrc/packages/NetBSD/$(uname 
-m)/6.0/All
# dhclient
# pkg_add py27-matplotlib
# python2.7 -m matplotlib.backends.backend_agg
