Actually, you can't currently use VFS modules on a FreeBSD system, as
configure checks if libdl is available and vfs.c depends on HAVE_LIBDL.
But on FreeBSD (at least 4.5) dlopen and such are part of libc and not
part of an own lib. Attached is a small patch for configure.in, which
"fixes" this issue (it's just a q&d hack I did after sb complained for
being not able to use my vscan-samba stuff on his FBSD system). Comments
welcome.

cheers, Rainer
