libmpcdec.so is provided by media-libs/libmpcdecsv7-1.2.6 as well as media-sound/musepack-tools-458. This appears intentional as the package descriptions lead one to believe that the musepack-tools package is to replace the libmpcdecsv7 package. If this is the case, then the ebuilds involved should be modified to reflect this. Reproducible: Always Steps to Reproduce: 1. emerge media-libs/libmpcdecsv7-1.2.6 2. emerge media-sound/musepack-tools-458 3. Actual Results: musepack-tools-458 fails to install due to an attempt to overwrite /usr/lib/libmpcdec.a and /usr/lib/libmpcdec.so Expected Results: A clean install It seems likely that simply unmerging libmpcdecsv7 before merging musepack-tools will solve the problem, although I do have some programs that link with libmpcdecsv7 and its not clear if they will work with the version of the library provided by musepack-tools. I'm testing that now.
I don't see any failure posted here, libmpcdecsv7 sources have been explicitely modified to install libmpcdecsv7.so instead of libmpcdec.so. That said, libmpcdecsv7 is now useless since everything has been ported to musepack-tools (still waiting for xine-lib and audacious go stable, and cynthiune patch to get applied).
Closing.. since it's impossible that libmpcdecsv7 would install libmpdcdec.so
