Suggestions to avoid trouble: automate as much checking as possible.

New top-of-tree and new builds with License: GPL should be flagged and
the maintainer should be asked to replace that with one of GPLv2,
GPLv3, GPLv2+, GPLv3+, and perhaps other combinations thereof.
Likewise for LGPL.

New builds that change licensing terms should check any library
dependencies for license incompatibility.  E.g., a GPLv2 program must
not depend on a GPLv3+ or LGPLv3+ library, and a GPLv3+ program must
not depend on a GPLv2 library.  (not sure about GPLv3+ / LGPLv2
compatibility, I haven't thought much about it, and IANAL :-)

New builds containing libraries should check any dependent packages
for license incompatibility similarly.
