dev-ruby/rubygems/rubygems-1.1.0.ebuild: Unquoted Variable on line: 27 26. PATCHES="${FILESDIR}/${P}-setup.patch 27. ${FILESDIR}/${P}-dependency-installer-install-dir-fix.patch 28. "
Actually, the check is working correctly because your quoting is unsafe for whitespace in ${FILESDIR}. Btw, in svn we've got a new "ebuild.patches" check that generates a warning if PATCHES is not defined as an array.
The "ebuild.patches" check is in 2.1.5_rc1.
