That is the intended behaviour. 'equery uses' only greps the use flags
for installed packages. If you want non-installed packages, you need
to use the '-a' flag

i.e.

[02:00 PM]wwong ~ $ equery uses '>=mysql-4.0.26'
[ Searching for packages matching >=mysql-4.0.26... ]
[ 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 dev-db/mysql-4.1.14 ]
 U I
 - - big-tables  : Make tables contain up to 1.844E+19 rows
 - - berkdb      : Adds support for sys-libs/db (Berkeley DB for MySQL)
 - - debug       : Tells configure and the makefiles to build for debugging. Effects vary across packages, but generally it will at least add -g to CFLAGS. Remember to set FEATURES=nostrip too

 - - minimal     : Install a very minimal build (disables, for example, plugins, fonts, most drivers, non-critical features)
 + + perl        : Adds support/bindings for the Perl language.

This is the same behaviour as all other equery commands: by default only
the installed packages are displayed.
