If you want libcanberra and therefore you must have USE="gtk", but you do not 
want to have any other packages compiled with the gtk USE flag, you can define 
it only for the package in question by adding a line in 
/etc/portage/package.use like so:

media-libs/libcanberra gtk -oss

to e.g. enable the gtk and disable the oss flags.

To see whether a flag has been set or not and relevant information about it, 
run:

euse -i <flag>

For libcanberra it shows:

[- cD ] gtk (media-libs/libcanberra):
Enables building of gtk+ helper library, gtk+ runtime sound effects and the 
canberra-gtk-play utility. To enable the gtk+ sound effects add canberra-gtk-
module to the colon separated list of modules in the GTK_MODULES environment 
variable.

Use option -I to see which packages have been installed using a particular 
flag.  Have a look in man euse to decipher the symbols.


To see all the flags for a particular package after it has been installed run:

equery uses libcanberra
[ Searching for packages matching libcanberra... ]
[ Colour Code : set unset ]
[ Legend : Left column  (U) - USE flags from make.conf              ]
[        : Right column (I) - USE flags packages was installed with ]
[ Found these USE variables for media-libs/libcanberra-0.26 ]

Architecture)

Have you read and applied http://www.gentoo.org/doc/en/xorg-config.xml to find 
out how to configure your card and xorg?
