[vtkusers] Problems building fresh CVS checkout on FreeBSD

[David D. Marshall]

Having never used FreeBSD, this may not help, but I think that the compiler 
command needs a -shared flag to tell the linker to create a shared library 
and not an executable (that's why it's looking for the main function).  Check 
the autoconf log to see why it didn't put the -shared flag in.

of people whatever they need to have done, but cannot do at all,
or cannot so well do, for themselves in their separate and
individual capacities.  -- Abraham Lincoln
