Not a lawyer, caveats abound, and all that, but;
Excerpt from GPL's licence FAQ:
*The program dynamically links plug-ins, and they make function calls to
each other and share data structures, we believe they form a single
program, which must be treated as an extension of both the main program and
the plug-ins. This means that combination of the GPL-covered plug-in with
the non-free main program would violate the GPL.*
So, it sounds like either way you're likely to need to release under GPL
or find a different library.
