I can reproduce here - it looks like another visibility bug rearing its ugly 
head. See -fvisibility-inlines-hidden in the error message. Busy now but I will 
try to patch soon if noone beats me to it... 

Marcus: If you want to touch it, please have a look at my attachment at Bug
98425. Apart from the one function to be moved to kde.eclass, the ebuild is
missing documentation, because since Digikam 0.7.4 it is provided as extra
tarball. This version should fix amd64 issues, too.

Seems to be on a related issue, and the ebuild attached to that bug fixes this  
issue. I am testing now, but it seems to have worked just great here too  
Carsten. It is late, but I will try to get to adding the docs to the ebuild and 
moving the function to kde.eclass tomorrow. Thanks.

You can take a look at the quick fix in gwenview-1.2.9x. Disabling visibility 
stuff is not needed anymore at a global level, because there's an improved 
configure check in KDE scripts that recognizes that visibility stuff should not 
be enabled (without a patched Qt). As this check propagates (as it did in 
digikam-0.7.4) nothing will be needed. For 0.7.3 doing as in the gwenview 
ebuild is enough.
