I guess the > script is just buggy. Thanks for the report. I think the build script is buggy, too. There is something about our systems, possibly some use flag, which is driving make crazy. There doesn't appear to be any action in emerge which unpacks the build files (or even the entire source) of a package for perusal. This is a shame. At this point, I have to ask myself whether spending time trying to debug it (or even to report the bug usefully) is better than simply tolerating the long build time. It doesn't seem like there'll be an easy solution. > Regards, > Florian Philipp -- Alan Mackenzie (Nuremberg, Germany).
