Don't confuse these two. LGPL contains an explicit permission to link to 
an unmodified library without importing the GPL conditions into your 
code. GPL does not. That's why there was all the fuss when MySQL changed 
the licence on their libraries from LGPL to GPL (don't even get me 
started about the ethics of applying a more restrictive license to your 
work after you've been distributing it for years).
