notfound 512190 1.1.5-3 found 512190 1.1.5-4 thanks 512190 only affects the version in unstable, the one in testing is fine.
512190 appears to be the result of fixing 508975 by removing use of shlibs and adding hardcoded dependencies in it's place. Using hardcoded dependencies for shared libraries is not reccomended since libraries can have different names on different architectures (as mentioned in this bug) and rebuilding a package on a system with a different version of the libraries development files may change the versions of the library it can work with.
Better soloutions to that bug would have been (in order from least hacky to most hacky) * get libruby to use symbols files so packages only pick up dependencies on the version that is needed for the symbols they actually use.
* use a shlibs.local file to override the shlibs versioning from libruby -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
