This library seems not to be in portage. It is used for creating and parsing messages with MIME content, at the Moment at least from balsa 2.2.* and depends on glib2. As category I suggest dev-libs. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Created attachment 35488 [details] ebuild (dev-libs/gmime-2.1.7.ebuild)
Above ebuild works version-bumped for the newer gmime-2.1.9 needed for balsa 2.2.5
Created attachment 41127 [details] gmime-2.1.9 Ebuild Ebuild for 2.1.7 only functions as long as one doesn't have USE="doc" I think. It uses db2html to create documentation, which I couldn't find in any package. But there is a sgml2html in the sgmltools-lite package, which does the job. So I added a line with sed. If there actually is a db2html somewhere, a dependency should be added to the ebuild for it.
db2html was a former name of docbook2html -- found in docbook-sgml-utils. (<http://sources.redhat.com/cgi-bin/cvsweb.cgi/docbook-tools/docbook-utils/bin/Attic/db2html?cvsroot=docbook-tools>)
I've changed the sed line to change db2html to docbook2html, as tove suggested, and documentation gets build properly. Thanks for the info! Ebuild is in CVS now, should be arriving on mirrors shortly. Thank you both, guys.
