1) corrupt chars in src_install; look for "prepare manpages" 2) sed usage + bash quoting rules: you don't need to escape whitespace that's already quoted, nor do you need to escape /, nor do you need escape '='... generally speaking, if you need " chars in an arg, use the alt quoting (single) or $''. Said sed line also seems to have a tab slapped prior to the last arg (minor in comparison to the sed). 3) invoking gzip directly for man pages is evil. Use appropriate functionality instead...
4/ dodoc COPYING INSTALL is not useful, it's already installed and has its license in ${PORTDIR}/licenses
Fixed.
