ALOE has been configured successfully. You can compile and
install it by typing 'make && sudo make install'

After that, you can run P-HAL by typing 'runph example-work' 
(see README for more information).

You can choose other compiler flags, e.g.:

include debugging symbols and enable symbol resolve:
	./configure CFLAGS='-rdynamic -O0 -g'

optimize for native processor including SSE instructions 
	./configure CFLAGS='-O3 -march=native -mfpmath=sse
