/usr/bin/convert is linked against libltdl.so.3 which is part of libtool so it must be a runtime dependency.
Created attachment 160469 [details, diff] Patched ebuild for imagemagick-6.4.0.6
Maybe it can be avoided to use libtool as a runtime dependency if "--enable-ltdl-install" is appended to imagemagick's configure command. In my case the following is installed: libltdl.a libltdl.la libltdl.so -> libltdl.so.7.1.1* libltdl.so.7 -> libltdl.so.7.1.1* libltdl.so.7.1.1* This may conflict with a regular installed libtool package...
(In reply to comment #2) > This may conflict with a regular installed libtool package... > And this is exactly the reason why I don't see it happening. Still, it probably should be made a runtime dependency then.
10 Aug 2008; Markus Meier <maekke@gentoo.org> imagemagick-6.4.2.0.ebuild: sys-devel/libtool is also required in RDEPEND (/usr/bin/convert links against libltdl.so*), bug #231892 Thanks for the report.
