Tree v1.5 has been released. An updated ebuild is attached. Reproducible: Always Steps to Reproduce:
Created attachment 39473 [details] tree-1.5 ebuild ebuild tested and working on my gentoo. YMMV.
Created attachment 39474 [details, diff] tree-1.5.ebuild (diff against tree-1.4.ebuild) Thanks for your ebuild, but in the future please post a unified diff instead of an entire ebuild that is essentially a duplicate of the existing in-tree ebuild.
Version bumped in CVS. Thanks for the bug report.
