TL;DR: Can't rebuld without readline because profile forces it on. You can override this, but do so at your own risk (or at least, not at mine). More info: If you had included the line showing the package and use flags, I could tell for certain, but I would guess that it's because the readline USE flag is force-enabled in the base profile. This is indicated by brackets '()' around the flag. You can override this by creating the directory /etc/portage/profile and adding the following text to the file 'package.use.force': app-shells/bash:0 -readline You should then be able to rebuild bash without the readline USE flag enabled, however I'm not sure if that's an entirely wise thing to do - it's force-enabled as part of the base profile (which leads me to thing disabling is a bad idea), but the comment for it [1] notes: # Force app-shells/bash[readline] in stage1 builds, so that compgen is # available for sys-apps/portage (see bug #445576). Bug #445576 [2] seems to indicate portage has a problem with bash's readline implementation (at least >=bash-4.2), but I don't know if that's still valid or not. If only to see if this problem is bash's readline, you can disable the force on the profile using the file above then quickly rebuild bash using it's built-in with USE="-readline" emerge -1aOv app-shells/bash This way you don't have to worry about remembering to remove a package.use (though you'd still have to remove the profile override). Hope this helps. [1] /usr/portage/profiles/base/package.use.force [2] https://bugs.gentoo.org/show_bug.cgi?id=445576 -- wraeth <wra...@wraeth.id.au> GnuPG Key: B2D9F759
