[gentoo-dev] qiv emerge failure

[Gontran]

emerge qiv-1.6.ebuild, fails to retrieve dependencies from imlib and gtk ...
did however properly retrieve the libtiff dep though. I'm concerned I don't
have my USE variable set properly...

Here is pertinent section from my /etc/make.conf:
---- /etc/make.conf ----

USE="slang readline gpm berkdb gdbm tcpd pam libwww ssl lm_sensors lvm pcmcia-cs
 alsa nls mmx mitshm esd lcms gif sdl vorbis ogg gnome gtk X motif opengl mozill
a fbcon"

---- /etc/make.conf ----

Here's the make failure:

Do I need to modify my make.conf USE variable to catch these deps?

TIA,
