Item #10 of v1.9 of the OSD says :

10. License Must Be Technology-Neutral

"No provision of the license may be predicated on any individual technology or style of interface."

Now look at the LGPL, and we find phrases in section 5 like "linking", "executable", "material from a header file", "object code for the work", etc....

I'd be interested to know how the OSI explains this...
