#24 libbitcollider.so no longer links to libdl.so.2

[Myers Carpenter]

When I try to link to libbitcollider.so I get

undefined symbol: lt_dlerror

Now, admittedly I'm not creating a c program to access
this, but rather ctypes for python

http://starship.python.net/crew/theller/ctypes/

Which lets me link to so/dll files w/o a complier. The
change is in bitcollider/lib/Makefile.am

In 0.4.0 looked like:
libbitcollider_la_LIBADD = $(LIBLTDL) $(BDB_LIBS)

But in 0.6.0 looks like:
libbitcollider_la_LIBADD = $(BDB_LIBS)
