Hi,
You don't compile with libusb-compat support. An application (like
pyusb 0.4.x) simply builds against the libusb-0.1 interface, and at
run-time it links either a libusb-0.1 "real" library or a
libusb-compat library. Normally you only have one of these installed.
If you have both installed, it depends on the run-time linker which
one is picked (see ld.so.conf or LD_LIBRARY_PATH).

If your doing static builds, the one that the build linker picks will
be included. If you have both on your machine, you can massage the -L
options (e.g. through LDLIBS in makefiles) to search the right
directories first.

On typical Linux distributions, the package management assures that
only one of them is installed.
