>Description:
POPEN function is used on many packages requering LUA, such as www/ion3-devel package. The absence of this avoids the full corectly run of certain apps (like ion).

USE_POPEN function must be activated manually on lua Makefile on certain operating systems.

Error of wm/ion3-devel on my system:

Ion startup error log:
>> Errors starting ion-statusd:
   /usr/pkg/lib/ion3/bin/ion-statusd: statusd_load.lua:43: 'popen' not supported


On a Makefile this appeared, maybe it can be useful for solving the problem:

    # If your system is not POSIX but has popen and pclose, define USE_POPEN=1.
    # If you don't want to support pipes, define USE_POPEN=0.
    #


This seems a known "bug" on this pkgsrc package, as show on the following urls:
http://cvsweb.de.netbsd.org/cgi-bin/cvsweb.cgi/pkgsrc/lang/lua/Makefile (find popen)
http://lists.freebsd.org/pipermail/freebsd-ports-bugs/2005-July/061289.html



>How-To-Repeat:
Build www/ion3-devel and using it will show the problem, not remember about other apps giving the same error.
