On MacOS X, when installing SWI-Prolog using DarwinPorts (including  
the installers available from the SWI-Prolog web site), the above  
header files are installed on /opt/local/lib/swipl-x.y.zz/include/. A  
possible solution would be to create links to the header files on / 
opt/local/include/.

> P.S. BTW, why /opt/local instead of /usr/local?

To ensure that DarwinPorts installed software does not depend or  
interfere with MacOS X provided software and libraries, creating a  
nightmare of dependencies (not to mention that upgrading MacOS X can  
wipe out /usr).

Cheers,

Paulo
