I'm looking for a good photo manager. Both digikam and shotwell look like good candidates, but since I am using gnome I would like to give shotwell a shot.

According to their website I need to build this on my own because Centos is not on their list of downloads available. They then go on to list all the dependencies.

Shotwell's dependencies include:

gconf-2.0 (2.22.0)
gee-1.0 (0.5.0)
gexiv2 (0.2.0)
gio-unix-2.0 (2.20)
glib-2.0 (2.26)
gmodule-2.0 (2.24.0)
gstreamer-0.10 (0.10.32)
gstreamer-base-0.10 (0.10.32)
gstreamer-pbutils-0.10 (0.10.32)
gtk+-2.0 (2.18.0)
gudev-1.0 (145)
libexif (0.6.16)
libgphoto2 (2.4.2) (Note that 2.4.6 has a bug that prevents Shotwell from fetching EXIF metadata before importing a photo.)
libraw (0.9.0)
libsoup-2.4 (2.26.0)
libxml-2.0 (2.6.32)
m4 (1.4.13)
sqlite3 (3.5.9)
unique-1.0 (1.0.0)
vala (0.11.7)
webkit-1.0 (1.1.5)


After about the first couple I realized most if not all of them are not going to be in my default repos.

So does this mean I need to go through and download each one manually from the links they give before building from tar or is there a repo I can add and then install from terminal?

Shotwell version 0.2.0 will work on the Fedora 12 based CentOS 6, I guess :
Shotwell-0.2.0 works on Fedora 12.

Later Shotwell's require glib / gtk versions, not available for CentOS 6.
( 500..600 applications depend on the installed versions : Gnome may not
work OK if later glib / gtk is installed.)

CentOS 5 : Not much chance, unless you build a static version
on a later Linux OS.
