I'm just starting out with Gentoo and I'm getting a bit stuck installing programs with Portage. It's wonderful and automatic except when it isn't.Many of the programs I try to install (git, gedit, chrome, nautilus) eventually depend on pth, whatever that is. But it fails with an econf error:   ERROR: dev-libs/pth-2.0.7-r3::gentoo failed (configure phase):     econf failed   Call stack:            ebuild.sh, line   93:  Called src_configure          environment, line 2881:  Called econf '--disable-static'     phase-helpers.sh, line  577:  Called die   The specific snippet of code:                die econf failed   If you need support, post the output of `emerge --info '=dev-libs/pth-2.0.7-r3::gentoo'`,   the complete build log and the output of `emerge -pqv '=dev-libs/pth-2.0.7-r3::gentoo'`.

econf fails when installing pth
gentoo;emerge
It turns out that /tmp was not writable except by root, for some reason. I fixed the problem withchmod a+w /tmpI have no idea how this came to be; it's a fresh install and I certainly didn't intentionally change the permissions to drwxr-xr-.
