No. Apparently the "-u" option is wrong: the mathematical library is used, 
otherwise how could the Sin() interpreter function work? libdl is used for 
loading component, and libpthread is needed by some components too, but not by 
the interpreter directly.

Moreover, as the interpreter usually loads components at program startup, you 
will have to add all the dependencies of these components.
