I had this problem a while ago (actually soon after I used the very
useful feature of user symbols).
The way to get around is to redefine the symbol to nothing in your layout:
## hide user define symbols
# symbol-hide line u:mylinesymbol
code metapost
def l_u_mylinesymbol (expr P) = enddef;
endcode
Of course it would be better to have symbol-hide working on user-defined
symbols but this is still feasible in many cases.
Hope that helps.
