After checking out everything to ~/scheme i needed to do
ikarus --r6rs-script ~/scheme/box2d-lite/demos/small-pyramid.sps
called from home would give me:
This is under OSX with "Ikarus Scheme version 0.0.4-rc1+, 64-bit (revision 1870, build 2012-11-19)" from macports.
Hi Anes. Add ~/scheme directory to your IKARUS_LIBRARY_PATH environment variable.
