New release of the flash plugin Adobe has provided version number for the tarball (woohoo) by the release date ebuild attached (basically a slightly tweaked version of the prev ebuild) Reproducible: Always
Created attachment 132332 [details] netscape-flash-100107.ebuild works fine this end (amd64)
It should be noted that this is a Release Candidate, but it should be made final in a short time if no bugs are reported to Adobe.
Well, there's no way I'm going to call this "netscape-flash-100107.ebuild", but I'll be checking in "netscape-flash-9.0.60.0_beta100107.ebuild in the near future. I have had no problems with it either, thus far (5 minutes of testing total), so it is not yet p.masked at this time.

Just one question: Why do you format it "netscape-flash-MMDDYY"? Emerge and derivates will mess up the release order. "netscape-flash-YYYYMMDD" would be the correct syntax.
