I'm a new linux user, and I'm following the instructions at 
http://wiki.gentoo-portage.com/HOWTO_Installing_3rd_Party_Ebuilds
on installing 3rd party ebuilds.

I've saved the ebuild file as /usr/local/portage/sys-fs/captive-ntfs/captive-1.1.5.ebuild and another copy at /usr/portage/sys-fs/captive-ntfs/captive-1.1.5.ebuild

Please help me!
