Since 'net-p2p/mldonkey' and 'app-emacs/mldonkey' it might be good to rename "app-emacs/mldonkey" to "app-emacs/mldonkey-emacs" or similar. Reproducible: Always Steps to Reproduce:
$ sudo emerge mldonkey Calculating dependencies !!! The short ebuild name "mldonkey" is ambiguous. Please specify !!! one of the following fully-qualified ebuild names instead: app-emacs/mldonkey net-p2p/mldonkey There are several other ports in the same situation, which is why portage detects the ambiguous case.
I knew this - just thought one would try to avaid it, which is quite easy in this case, i think :) Okay. Now i know better...
