font.com wasn't corrected anymore after last version bump, because the version number inside the sed statement wasn't corrected. The supplied diff correct this and makes it more generic.
Created attachment 170409 [details] nmrpipe-9.27.2007.222.14.56.ebuild.diff Patch for the sed statement.
Was removed from Portage same time with deprecated XView library, you can still find the ebuild from http://sources.gentoo.org
