The amd64-linux/lib is a directory in the workspace. There is another 
amd64-linux directory in the compiled protocol's directory. This 
directory has symlink called lib which points to a non-existant 
direcotory in the workspace. This could possibly be a bug. I'm not sure 
if the following screenshot will help. In the following case 
$GEMS=/tmp/ranji/simics64/gems64, 
$SIMICS_INSTALL=/tmp/ranji/simics64/simics-3.0.19. The $GEMS/amd64-linux 
is a directory. But the link $GEMS/simics/targes/MOSI_SMP_bcast/lib -> 
amd64-linux/lib which in turn points to ../../../x86-linux/lib which is 
non-existant.

However, I installed gems1.3.1 and I'm able to load ruby successfully!
