ebuild question

hi, i found this piece of code on the net for the ebuild command that works for a gentoo box.

Code:

DESCRIPTION="Name Service Switch module for use with PostgreSQL" HOMEPAGE="http://pgfoundry.org/projects/sysauth/" SRC_URI="http://pgfoundry.org/frs/download.php/605/${P}.tgz" LICENSE="GPL-2" SLOT="0" IUSE="" DEPEND="dev-db/libpq app-text/xmlto" RDEPEND="${DEPEND}" src_unpack() { unpack ${A} cd "${S}" epatch "${FILESDIR}/${P}-gentoo.patch" epatch "${FILESDIR}/${P}-schema.patch" epatch "${FILESDIR}/${P}-setgrent_fixed.patch" eautoreconf } src_compile() { econf \ --libdir=/lib \ --with-docdir=/usr/share/doc/${PF}/html || die "econf failed" emake || die "emake failed" } src_install() { insinto /$(get_libdir) doins src/.libs/libnss_pgsql.so.2.0.0 dosym libnss_pgsql.so.2.0.0 /lib/libnss_pgsql.so.2 dosym libnss_pgsql.so.2.0.0 /lib/libnss_pgsql.so dodoc AUTHORS ChangeLog NEWS README dohtml doc/*.{png,html} insinto /usr/share/doc/${PF}/examples doins conf/* } pkg_postinst() { elog "Next steps:" elog "1. Create the required tables in the database:" elog " $ psql a_database -f ${ROOT}usr/share/${PN}/conf/dbschema.sql" elog "2. Create the configuration file '/etc/nss-pgsql.conf'" elog " You can copy the example from ${ROOT}usr/share/doc/${PF}/examples/nss-pgsql.conf" elog "3. Edit /etc/nsswitch.conf to use the NSS service 'pgsql'" elog " An example is available here: ${ROOT}usr/share/doc/${PF}/examples/nsswitch.conf" }

i have no idea what this command does and was hoping someone can help me translate the code to something that will work for a fedora core 6 box.
