Version 0.1.6 has been released. Renaming the ebuild works, though you *must also* change SRC_URI to the new naming scheme: SRC_URI="http://files.libburnia-project.org/releases/${P}.pl00.tar.gz" (note the pee-ell-zero-zero at the end) Tested on amd64; compiles and runs just fine.
Forgot to mention that it depends on >=libburn-0.4.8 and >=libisofs-0.6.4, which is why libisofs-0.6.6 needs to be added to the tree. Bug 224533 and bug 224539, respectively.
Should have checked bugzilla first.. anyhow.. 0.1.8_p0 in tree, thanks for reporting nightmorph :)
