No.  LGPL is approximately equivalent to GPL+LGPL.  The source files are
LGPL (in case someone takes them out and uses them for some other project).
The combination is GPL.

Basically, whenever you add a bit of GPL to an LGPL thing, you get GPL --
but the LGPLed bits remain LGPL in case someone wants to separate them out
and use them for something else.

Bush admitted to violating FISA and said he was proud of it.
So why isn't he in prison yet?...
