At the moment of the writing, ecb is still version 2.27 in portage, and 2.31 is out. Please note that both versions have trouble with latest emacs-cvs (the one I use is from ~ 07/01/2005), and I haven't tested it with the "normal" GNU Emacs release. The ebuild needs to be slightly changed, simply renaming doesn't work. Probably just editing: make ${CEDET} \ LOADPATH="${my_loadpath}" \ || die "make failed" to: make CEDET="${CEDET}" \ LOADPATH="${my_loadpath}" \ || die "make failed" will sufficit.
Created attachment 51318 [details] ECB 2.31 Ebuild
Created attachment 51319 [details] ECB 2.31 Digest
I have added the ECB 2.31 Ebuild and Digest files as attachments. I have successfully used these to extract ECB 2.31 and have it installed. I have also attached my session file to show that it did work.

updated in portage, thanks for the report.
