Try to emerge musicman >= 0.11 (older ones not tested): [ebuild N ] media-sound/musicman-0.15 -arts -debug -kdeenablefinal +xinerama 0 kB on an aRts-free KDE system. The ./configure gives you: checking for KDE paths... defaults checking for dcopidl... /usr/kde/3.5/bin/dcopidl checking for dcopidl2cpp... /usr/kde/3.5/bin/dcopidl2cpp checking for mcopidl... not found configure: error: The important program mcopidl was not found! Please check whether you installed aRts correctly. !!! ERROR: media-sound/musicman-0.15 failed. !!! Function kde_src_compile, Line 156, Exitcode 1 !!! died running ./configure, kde_src_compile:configure !!! If you need support, post the topmost build error, NOT this status message. Possible solutions: When possible, make musicman compile without aRts. In the case it realy depends on aRts (which provides mcopidl?) add arts to the depend.
I think the problem is not that it requires arts, but that it's using an older admin directory. I'll give a look at that later today.
Added check to make sure arts is enabled.
