This is an as-yet unresolved incompatibility between Tiger and Leopard. 
For Leopard, you have to patch the file glrender.h, where these triple 
dots are introduced (you will see where) and remove them. The asymptote 
authors are trying to find a patch that will work on Tiger, too (the 
above manipulation makes it break on Tiger), but until now, they haven't 
found one. See
