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...
