Perhaps, the start of the emerge is also interesting:

Comment 3 Albert Zeyer 2006-10-17 13:47:11 UTC
And last but not least, these are the set USE-flags for my emerge:

[ebuild     U ] media-gfx/showimg-0.9.5 [0.9.4.1] USE="exif%* mysql%* -arts -debug -kipi% -postgres% -xinerama (-kdeenablefinal%)" 0 kB
Comment 4 Wulf Krueger (RETIRED) gentoo-dev 2007-04-27 14:52:08 UTC
Do you still have this problem? I can't reproduce it using your USE flags.
Comment 5 Carsten Lohrke (RETIRED) gentoo-dev 2007-04-30 15:12:04 UTC
First thing I notice is 

sys-devel/binutils:  2.15.92.0.2-r1, 2.15.92.0.2-r10, 2.16.1-r3

Please do `emerge binutils libtool` make sure you have no kde*.eclass files in your overlay and tell us, if this is still an issue.
Comment 6 Albert Zeyer 2007-05-02 06:03:37 UTC
It seems to work now, thanks. :)
But the strange this is, I haven't really changed anything (despite of some system updates from time to time). (Was there an update in the ebuild?)

The USE-flags for showimg haven't changed:

acomputer ~ # emerge -pv showimg

These are the packages that would be merged, in order:

Calculating dependencies                             ... done!

Comment 7 Carsten Lohrke (RETIRED) gentoo-dev 2007-05-02 10:33:53 UTC
Albert, you're doing something wrong, when you have multple binutils ebuilds listed in your emerge --info output. Take more care when updating your toolchain and make sure _never_ to set the AUTOCLEAN variable to "no", as one of the possible sources of such problems.


Comment 8 Albert Zeyer 2007-05-02 18:51:33 UTC
I never have set AUTOCLEAN to no myself and I don't think, that some of the other tools I use from time to time (revdep-rebuild and similars) do this, don't they?

But perhaps this is related to the long history of world updates - this Gentoo installation was installed in July, the 16th in 2004.

Is it save to do a 'emerge -pv -C \<binutils-2.16.0'? What else should I do to clean up my system? Should a 'emerge --depclean' solve all problems (but it doesn't show any interesting packet)?

Thanks and Greetings,
Albert
