I'm afraid this is wrong.
Distribution is not a requirement but referencing is. You cannot just
wrap a GPL library in BSD code and then "pretend" it is no longer GPL
unless you have the right to do so.
The following is taken from the GPL FAQ:

Can I release a non-free (i.e. anything not GPL) program that's
designed to load a GPL-covered plug-in?
It depends on how the program invokes its plug-ins. For instance,
if the program uses only simple fork and exec to invoke and
communicate with plug-ins, then the plug-ins are separate programs, so
the license of the plug-in makes no requirements about the main
program.
If 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. In order to use the GPL-covered plug-ins,
the main program must be released under the GPL or a GPL-compatible
free software license, and that the terms of the GPL must be followed
when the main program is distributed for use with these plug-ins.
If the program dynamically links plug-ins, but the communication
between them is limited to invoking the ‘main’ function of the plug-in
with some options and waiting for it to return, that is a borderline
case.
Using shared memory to communicate with complex data structures is
pretty much equivalent to dynamic linking.

Since DbLinq is designed to load Ingres and MySQL data providers and
interact with them, DbLinq is a GPL program and you have the choice to
either:
1. Change the license to GPL
2. Remove MySQL and Ingres from the project. (This is the best
solution in my opinion).
