digikam-0.6.1 fails build

[Dennis Veatch]

Looked on Sourceforge and that version is not listed but 0.6.2 is. So I bumped 
the module, still fails build because neither version can be found on any of 
the servers lin uses.

Following the websites download link takes you to sourceforge and 0.6.1 is not 
listed but 0.6.2 is. Looking in http://digikam.free.fr/Tarballs (the first 
download source) is completely empty.
