modules/plugins/libraries

Hi Al.

I get the following when loading a plugin

> load ./s_dc2.so
       ^ ? ./s_dc2.so: undefined symbol: SIM::outdata(double)

SIM::outdata(double) comes from apps/s__out.cc, which is not part of
libgnucap.so but libgnucap_default_plugins.so. is this intended?

also, libgnucap_default_plugins.so should imo be
gnucap_default_plugins.so, and, like other plugins/modules, it should
not be linked against (but against libgnucap.so).

regards
felix
