It's not quite the same, scons' cache feature needs to be explicitly enabled in the SConstruct file, I don't think many projects have it enabled... See the scons manual: http://www.scons.org/doc/0.98.5/HTML/scons-user/c3143.html A NO_CCACHE might be useful for ports that do have this cache enabled, but are there any ports at all which use this? As a sidenote, AFAIK cons and scons are not related... -- Martin Tournoij carpetsmoker@rwxrwxrwx.net http://www.daemonforums.org QOTD: The fact that Hitler was a political genius unmasks the nature of politics in general as no other can. -- Wilhelm Reich
