dev-lang/j has several problems in build system so libj doesn't compile but build_libj doesn't return error so ebuild is marked as corrent Steps to reproduce: 1. emerge dev-lang/g 2. jc Actual results: You'll get: Load library /opt/j/bin/libj.so failed Expected results: jconsole should be started. Solution: add to src_prepare: sed -i -e 's:W1,soname:Wl,-soname:' bin/jconfig || die
Fixed in tree. Thanks Patrick for reproducing this problem.
