Would it be possible to add an ebuild for the 0.76cvs version of gaim? That appears to fix many problems with the Yahoo! servers.
Steps to Reproduce:
Definitely not. I cannot guarantee stability of their CVS tree and am not in the mood to support user bugs (which I would just mark as INVALID) on it. The Gaim developers themselves say NOT to use CVS unless you are developing against it or patching it.
gaim-0.75-r10 fixes yahoo web auth. Yes normal yahoo auth is fixed in 0.76.
gaim 0.76 should be out relatively soon.
