Bitlbee 1.0.3 released 24/06/2006. Have not yet been able to locate the msn patches for 1.0.3 however. 1000 miles from my gentoo box so I can't confirm or deny if it builds.
I'll attempt to put this into portage tomorrow, assuming the msn-extras patch for 1.0.3 is available. If not, I'll probably hold off on putting it into portage until the patch is available to keep the revision bumps down.
Just an update to say the patch has not been released yet.
Still no msnextras patch, but I've gone ahead and put 1.0.3 into portage without it. It should show up on rsync servers within the hour. Enjoy!
