Comment 22 for bug 275688

The four packages mentioned in this bug-report having build dependencies
 are licensed as follows:
imapcopy is GPL-2+
hedgewars is GPL-2
libhdate is GPL-3+
gearhead is LGPL-2+

I further found
m-tx is GPL-2+ (build depends on fp-compiler)
python-soappy is BSD-like (build depends on fpc)
poker-network is GPL-2 (build depends on python-soappy)

gearhead is a role playing game that does not have any depends or
reverse depends except it's own binaries.
