Builds flawlessly here on my hosts by just bumping the old 1.9.7.ebuild. Changes include: * The filter preferences dialog, the edit account dialog, and the folderview were reimplemented using GtkTreeView. * Auto-scroll on DnD was implemented. * GBK encoding is supported. * The broken PLAIN authentication for SMTP AUTH was fixed. * A workaround for some SMTP servers, which terminate connection right after QUIT command was sent, was made. * Clear-signed messages are not MIME-encoded anymore. * The line-wrapping of composition window was modified not to screw up itemized lines.
Fixed in CVS. Thank you for reporting.
