Description of problem:

I don't have evolution installed, I don't like it.
I use Thunderbird and wanted to use the Mozilla
calendar application as well on my desktop.
But Sunbird cannot be installed because of a
dependency problem.

# yum install sunbird
...

Error: Package: sunbird-1.0-0.33.b2pre.fc15.x86_64 (fedora)
           Requires: libnotify.so.1()(64bit)
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

# ls /usr/lib64/libnotify*
/usr/lib64/libnotify.so  /usr/lib64/libnotify.so.4  /usr/lib64/libnotify.so.4.0.0
# rpm -q libnotify
libnotify-0.7.3-1.fc15.x86_64

libnotify seems to have changed its library version
since Sunbird was compiled.

Version-Release number of selected component (if applicable):

# yum info sunbird

How reproducible:

Always.

Steps to Reproduce:
1. Install Fedora 15 without evolution (in my case I upgraded from Fedora 14 that was tailored to my needs)
2. Try to install sunbird.
3. Get disappointed.

Actual results:

Cannot install sunbird.

Expected results:

Sunbird can be installed and work, also announces itself in the gnome settings as a calender application.

Additional info: There is a light but cold autumn breeze outside. My russian blue cat sleeps on my bed because he doesn't want to get cold. :-)
