For the record: the solution

The problem was an incorrect path compiled into the library:

tron@excalibur:~>otool -L /usr/pkg/lib/libjs.dylib
-->	Darwin_DBG.OBJ/libjs.dylib (compatibility version 0.0.0, current version 0.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.1.6)

The fix is to link the library with "-install_name /usr/pkg/lib/libjs.dylib".
Thanks a lot to Amitai Schlair who helped me figuring this problem out.

And the good news for the Mac OS X "pkgsrc" users is that the "avidemux"
package now builds and works fine.

	Kind regards
