stepmania will fail to compile without libpng. At least it did for me. I figured it out by running the binary which died complaining about the missing library. I'm still having issues compiling but it seems to be getting farther. Reproducible: Always Steps to Reproduce: 1.emerge -C libpng (?) 2.emerge stepmania 3. I have looked through the bugs and found the gcc 3.4 issue but this doesn't apply to me. I am running it on a hardened profile though if that matters.
I'll look into it.
I've messed with it more and with libpng installed it is segfaulting during the build in random places. I've also pulled down the CVS code and found it to be equally bad. I haven't had problems like this before so i wouldn't say its hardware. I think I'd just say stepmania is a buggy build period that should should be fixed upstream. from the cvs comments it looks like they are trying to work on it. If I get time, I'll may make a binary ebuild for anyone else that might be having trouble.
Is this still an issue with 3.9 from bug #109535?
looks like it. libpng is pulled in as a dependency.
libpng is now pulled in as a dependency. Thanks for report
