Can you point me to the relevent portions of the license? I tried to go through the license, but it basically seemed free (as in GPL) to me. My impression is that you can't statically link Sleepycat's Berkeley DB with software unless it is released under a free license (reasonable, kind of like the GPL, if you consider that reasonable). They sell a commercial version, which allows you to statically link it. I sort of get the same idea from MySQL: as long as you aren't trying to distribute it, you're fine (even in-house changes). Also, aren't mysql and sleepycat in the standard distribution of Debian? I would think the debian developers would be interested to know if the likes of sleepycat and mysql don't abide by the DFSG. That's actually one of the things I've always liked about Debian: read one set of guidelines, and trust the developers to ensure compliance across the entire OS (as long as you stay our of non-free). At least, so I thought... Regards,Jeff Davis
