how to use linux .so in freebsd application

[Chicky ShnoodleSoup]

Hi,

Thanks to the linux binary compatibility
(http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/linuxemu-lbc-install.html),
I am able to run a linux application using the linux dynamic library
on a freebsd machine.

Now I am trying to get a freebsd application (same application but
compiled on freebsd) using the linux .so (don't have the source to
compile it on freebsd)  running on freebsd.

Is that possible? if yes, how to do it?
How to tell the compiler to use freebsd libraries for the application
and the linux ones for the linux .so?

Thanks,
C
