Created attachment 183490 [details] /var/tmp/portage/media-gfx/potracegui-1.3.4-r1/temp/build.log
Same problem here. Same as bug 255046. -r1 version didn't fix it!
Any news?
Linking works fine if all occurrences of /usr/lib are removed from the library search path. I assume the linker picks up the wrong version of libkdecore (and maybe other KDE libraries): it uses the library from /usr/lib instead of the KDE 3.5 library from /usr/kde/3.5/lib.
On a system where kde-base/kdelibs:4.2 is not installed, but only kde-base/kdelibs-3.5.10-r6 is, media-gfx/potracegui-1.3.4-r1 can be emerged without problems.
It is a dead kde3 project. Last release from 2005. I think, it is better to remove it from portage. Inkspace is already capable what this package does.
Created attachment 198679 [details, diff] Patch to work around the linking problem
Created attachment 198681 [details, diff] Patch for the ebuild file (potracegui-1.3.4-r1.ebuild to potracegui-1.3.4-r2.ebuild) to include the linking patch
On my system, the attached patches fix this problem. I haven’t looked deeply into it, but this is probably a bug/misconception in the build system or a general problem of conflicting library names. I’d say, that all_libraries should only include non-system library search directories. If someone comes up with a better patch, they’re welcome. :-)
Nico, your patch works for me (on x86). Thanks!
Thanks Nico. Your patches work on my ~amd64, too.
Hey Nico, the patch does not work for me.

Perhaps it’s just me, but … can anybody see the error message in comment 12? %-) Juergen, could you please attach a full build log? I am not a geek of compiler or linker flags or their order. Perhaps qa@ or some dev should have a look at this? graphics@, are you still with us? ;-)
Nico, thank you very much for this fix. Commited to the tree. JFI, this patch does not changes anything in program itself thus version bump is not needed.
