support was dropped for balsa on sparc because it depends on gmime, which is not supported on sparc. Please test gmime so support can be enabled.
gmime looks fine, ~sparc'ed 2.1.9-r1 since it's what balsa-2.2.6 wants. balsa-2.2.6 doesn't build yet for me, but that's because i'm using gnome 2.10, which in turn uses gtk+-2.6.4 and stuff which balsa doesn't build against yet. Waiting on John to commit a patch for balsa (keeping this bug open to find out when it happens, hopefully!), then testing again.
committed deprecation patch / updated ebuild, try it out in a bit. Thanks!
~sparc happy now, thanks.
