this was fixed yesterday in changeset 693faf7f439b

------- Comment #3 From Tom Henderson 2008-09-07 12:28:34 EDT -------

This bug seems to have crept back in:

machine:  ns-regression (gcc-4.2.3 Ubuntu x86)

[496/536] cxx_link: build/debug/samples/main-callback_2.o ->
build/debug/samples/main-callback
debug/libns3.so: undefined reference to `dlopen'
debug/libns3.so: undefined reference to `dlclose'
debug/libns3.so: undefined reference to `dlerror'
debug/libns3.so: undefined reference to `dlsym'
collect2: ld returned 1 exit status

(changing title to reflect new information)

This can be repeated by forcibly disabling gtk-config-store from the build (I
didn't see a waf option) and gtk.h won't get pulled in.  It can be solved by
installing or enabling gtk-config-store.

I can't reproduce this with any gcc I tried it on.

------- Comment #6 From Tom Henderson 2008-09-09 03:37:41 EDT -------

I couldn't reproduce again tonight, so it must have been fixed sometime today.
