ClanLib requires a correctly installed Hermes 1.3.0 or newer to run.
fix: comment out #exit;   in ./configure (but make sure you have Hermes installed)

Libraries have been installed in:
   /usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-LLIBDIR' linker flag
