Arch Linux

1) please add more information as how we can reproduce it
2) open a bug report in the right project

1.) * [ngaba@Arch ~]$ ldd `which transmission` | grep notify
libnotify.so.1 => /usr/lib/libnotify.so.1 (0xb7f5a000)
* /usr/lib/libnotify.so.1 is owned by libnotify package
* libnotify is not a dependency of transmission (this is the bug)

2.) Sorry.

Transmission does not require libnotify to run. Daemon mode works fine without it. If there should be any change at all, I'd say an optional depends.

I disagree. Then split transmission package. One of its component doesn't work without libnotify. You suggest, that the GUI is "not important". This is not an argument: This sounds like this: "foo is required by mkfifo only in coreutils, so put it to optdepends only."

Hm. gtk2 is not a dependency neither.
I've checked the install file, it says: "If you want to see notifications, install libnotify package".

I still say, that split would be better:
* if you don't need GUI, why should it sit on your HDD.
* if you need GUI, you also need its dependencies.

I don't really have a strong opinion on this, but if that didn't package is split, then I don't think we should split it.

uh.. Wow, I failed there. Meant to say, "If the authors didn't split it, we shouldn't"

Also, on http://wiki.archlinux.org/index.php/Arch_Packaging_Standards#Package_Etiquette it says:
Any optional dependencies that aren't needed to run the package or have it generally function shouldn't be included, but a warning message inside the .install file should echo something like: "To enable SMB support, download the Samba package."

Theres a post install message about libnotify
