When I have wanted to make sure that the lib subdir of the directory from
which the program executes is added to the load path, I use this:

#
# make sure we can pull in anything under the directory where the program is
# being executed
#
$LOAD_PATH << File::join(File::dirname($0), "lib")

seems to work for me.
