merged build doesn't build on Fedora 10

[Urs Rau]

On a fully uptodate fedora 10, I have downloaded from git, run
autogen.sh then cd'ed to source3 and run './configure
--enable-merged-build' followed by make.

It ran but then came up with the following missing functions:
event_add_fd
event_add_timed
event_add_timed' follow
event_context_find
event_context_init
event_context_init_byname
event_get_fd_flags
event_loop_once
event_loop_wait
event_set_fd_flags
ev_set_debug

What am I missing?
