Details:

Tested with revision 947 (as at 21 October 2010).

Attempts to build fail with:

...
gcc -Wall -g -O2   -o avrdude avrdude-main.o avrdude-term.o ./libavrdude.a
-lusb -framework CoreFoundation -framework IOKit  -lm -lreadline -lncurses
-ltermcap 
Undefined symbols:

  "_libusb_open", referenced from:
      _usbOpenDevice in libavrdude.a(libavrdude_a-usbasp.o)
ld: symbol(s) not found
...

This is on a Mac OS X 10.5 Intel system that has the following libraries:

/usr/local/lib/libusb-0.1.4.4.4.dylib
/usr/local/lib/libusb-0.1.4.4.5.dylib
/usr/local/lib/libusb-0.1.4.dylib
/usr/local/lib/libusb-1.0.0.dylib
/usr/local/lib/libusb-1.0.dylib
/usr/local/lib/libusb.dylib

Replacing "-lusb" with "-lusb-1.0" results in another different set of
"Undefined symbols" errors.

Revision 940 compiles successfully, revision 941 introduces the failure.

Two different workarounds made the compile successful:

  * Include both "-lusb" and "-lusb-1.0" in the compiler call.

  * Modify usbasp.c to only define "USE_LIBUSB_1_0" if HAVE_LIBUSB is not
defined. This forces use of libusb-0.1 even if libusb1.0 is installed. e.g. :

#if !defined(HAVE_LIBUSB)
#ifdef HAVE_LIBUSB_1_0
# define USE_LIBUSB_1_0
#endif
#endif

I haven't tested either of these modifications on any other system.
