stderr

Executable /usr/bin/APs/APserver not found.
This could means that 'apl' was not installed ('make install') or that it
was started in a non-standard way. The expected location of APserver is 
either the same directory as the binary 'apl' or the subdirectory 'APs' of
that directory (the directory should also be in $PATH).
