This sounds similar to the problem I had under Linux -
sys is builtin, time and math aren't, and the interpreter
symbols needed aren't available to the time and math
libs.

If you're using something like 'dlopen' to import the
interpreter, it needs to happen with the RTLD_GLOBAL
flag set. If you're statically linking, there's probably
an equivalent linker switch. I was using KDE which has
a method for globally loading libs. libtool looked
messier, but fortunately I didn't need to get into it.

man dlopen (at least for Linux).
