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.
