>Description:
print/freetype2 has a mechanism to autodetect the system it should compile on. (for example, ansi or unix). This autodetection mechanism relies on the fact that '/sbin/init' exists on every unix system. This is not necessarily true for FreeBSD jails, in which a paranoic system administrator would delete '/sbin/init' (it isn't useful in a jail anyway).

When attempting to compile print/freetype2 in such a jail, it will incorrectly detect the system as 'ansi' and stop with the following error:

===>  Building for freetype2-2.2.1_2

gmake: *** [objs/ftsystem.o] Error 1
*** Error code 2

Stop in /usr/ports/print/freetype2.

>How-To-Repeat:
First solution:
1) create a FreeBSD jail, as described in jail(8)
2) delete /sbin/init from the jail
3) install the ports collection
4) install print/freetype2

Dangerous, but should prove the point:
1) chflags noschg /sbin/init
2) mv /sbin/init /sbin/init.0
3) install print/freetype2
4) mv /sbin/init.0 /sbin/init
5) chflags schg /sbin/init

>Fix:
Workaround: type the following command in the jail environment:
touch /sbin/init

or, add the attached patch to print/freetype2/files
