The xpdf-3.02-r2.ebuild installs the xpdfrc man page from /usr/portage/app-text/xpdf/files/xpdfrc.5 which is an outdatet version (e.g. missing the options bind and unbind in section "Miscellaneous Settings"). The original xpdf source from ftp://ftp.foolabs.com/pub/xpdf/xpdf-3.02.tar.gz contains a newer xpdfrc.5 file. Reproducible: Always
xpdf-3.02-r4 doesn't install the file from ${FILESDIR} anymore.
