  By the way, if you're interested to know which symbols are exported
from a library, just do

  nm -D /usr/lib/library.so

  A look to that on my computer shows no references to flo_plus, only:
nm -D /usr/lib/libruby1.8.so | grep flo
                 U flock
                 U floor
0000000000057ef0 T rb_float_new

  Cheers
