Comment 66 for bug 501393

I tried to land this (http://hg.mozilla.org/mozilla-central/rev/99cdecb3734f), but will have to back it out because of this:

checking for libnotify >= 0.4... Package libnotify was not found in the pkg-config search path. Perhaps you should add the directory containing `libnotify.pc' to the PKG_CONFIG_PATH environment variable No package 'libnotify' found
configure: error: Library requirements (libnotify >= 0.4) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
