... and these are by far not all variants of the [L]GPLv2 ;)
Consider e.g. the "GPLv2 w/ <some exceptions>" and the "dual licensed
cases".

Also consider the impact on backporting patches against GPLv3'd versions
of a package to their GPLv2(+) predecessors. 

E.g. the GCC project currently is discussing the legal impact of
back-porting upstream (==GPLv3) changes to older releases (e.g. gcc-4.2)
and/or vendor forks/branches (such as Apple's GCC or RH's).



Also, though the FSF has a GPL* compatibility matrix, they don't provide
much help for other licenses' compatibility. I.e. at least I consider
the implications of GPLv3'd run-time packages on packages being licensed
differently to be widely unclear at this point in time.

To put it differently: To which extend is the old "GPL* vs. free-license
compatibility list" still valid?

That's what I wanted to express - There lies madness and insanity inside
of the license tagging.

IMO, it needs to be a copyright-specialized lawyer to be able to clarify
the situation. Neither the FPC, FAB nor FESCo are able to handle such
situations.

IMO, the rpm license tag is both: informative to end-users and a hint to
developers. Active developers will have to carefully check a package
"they use" or "derive their works from" in any case.
