Claws is holding back the upgrade of libetpan, so a rebuild is needed. Judging from the failed builds in koji, an attempt has been made but it was half a month ago. The libetpan upgrade was also marked as a security upgrade, so it would be nice if this could be sorted out soon.
Still fails to build: http://koji.fedoraproject.org/koji/taskinfo?taskID=706584 Also still causing broken deps in rawhide: Broken deps for i386 ---------------------------------------------------------- claws-mail-3.4.0-1.fc10.i386 requires libetpan.so.11 claws-mail-plugins-bogofilter-3.4.0-1.fc10.i386 requires libetpan.so.11 claws-mail-plugins-dillo-3.4.0-1.fc10.i386 requires libetpan.so.11 claws-mail-plugins-pgp-3.4.0-1.fc10.i386 requires libetpan.so.11 claws-mail-plugins-spamassassin-3.4.0-1.fc10.i386 requires libetpan.so.11 (from http://www.redhat.com/archives/fedora-devel-list/2008-July/msg00670.html )
Sorry for not responding. I have been busy with work... I am still not convinced this is a claws bug but I will see to get something working this weekend.
I don't know about i386, but I get the same libetpan dependency errors when I try to install x86_64 claws-mail on my F10 alpha boot partition.
It is really getting time to fix this. Claws is uninstallable on rawhide, and we who already have it cannot get the libetpan security fix in. There is both a new libetpan and new claws-mail out. Have you tried compiling that pair?
3.5.0 does not compile on rawhide because of gtk issues. This has been fixed upstream and I am currently waiting for the new release.
