The ebuild is (mostly) just a wrapper for preceding software installation tools, like make and gcc. In a previous message you showed us that the Gtypist devs had asked you "Can you check whether this appears when running ./configure? Also, which arguments are used for ./configure?" In the case of the nls USE flag, the ebuild is just calling configure with certain arguments: src_configure() { econf $(use_enable nls) } src_install() { emake DESTDIR="${D}" install } Note the IUSE variable. This lists all (non-special) use flags that are used by the ebuild. This is used for the emerge -pv output, amongst other things. The package's ./configure script takes the usual --enable-nls or --disable-nls argument. We use the use_enable utility function to generate this automatically, depending on the user's USE flags (see Query Functions Reference). This is a top google hit for use_enable: https://devmanual.gentoo.org/quickstart/ Stroller.
