blackdown-java3d-1.3.1 uses java-config -O internally to find JDK home. Older versions of java-config do not support this option.
I don't know exact versions but 1.2.6 understands -O flag and 0.2.8 does not.
Steps to Reproduce:
1. Find a system with an older java-config (e.g. 0.2.8)
2. emerge sync
3. ACCEPT_KEYWORDS=~x86 emerge blackdown-java3d
Many errors during install and merge phases, mainly sandbox violations.
Install java3d libraries into JDK's ext dir.
Fixed in portage, thanks.
Actually, java-config is a build-time dependence, not run-time. I have not mentioned that explictly and for that I appologise.
Good. Thank you for the quick response.
