I took a task a few weeks ago to investigate the Sleepycat license 
(http://www.opensource.org/licenses/sleepycat.php) to see if it was 
compatible with the MPL/LGPL and GPL in a way that would allow code 
released under it to be used by Mozilla.

As far as I can see, I'm afraid it's not. The problematic section is the 
following:

"Redistributions in any form must be accompanied by information on how 
to obtain complete source code for the DB software and any accompanying 
software that uses the DB software."

If a distributor of Mozilla, e.g. (for simplicity) Netscape, is using 
code under this license, they would have to make available the source 
code for their entire product. This is far more than the MPL requires - 
the MPL is only a file-level copyleft.

Therefore, I'm afraid, software under this license cannot be used in 
Mozilla. If this clause were modified, it might be possible - that would 
depend on the modification.
