the app-admin/realpath ebuild references an unavailable version of the package, 1.9.3. The next available version is 1.9.7, which when substituted in the ebuild operates as expected. I renamed the affected files to reflect dwww version 1.9.7 and recomputed the checksums, and everything operated flawlessly. This should be a quick and simple fix to replicate since I've packages the affected files at the site listed with this bug report (http://lemaymd.com/dwwwfix). I expect version 1.9.3 of the package contained a security flaw and was removed from distribution.
added realpath-1.9.10 to portage. thanks for the report.
