sadly, in this case, simply renaming the ebuild and changing the download tgz's name doesn't work. Also, AMD no long appears to have the old files online, so this better get into portage forpeople who want acml.
Here is an apparently working ebuild for 2.6.0. Some simple changes had to be done from 2.5.0, because the directory structure of the included tarball is different. Note the sse2 and sse options!
Created attachment 65879 [details] sci-libs/acml/acml-2.6.0.ebuild
Current version is now 2.7

Just a question...how was my bug (as mentioned in the last comment) a dup? I don't see anything here that's relevant to it.
I don't understand what is this bug about, really. 2.7.0 and 3.0.0 in portage, closing an obsolete bug.
