Target minimal xorg without development packages

Hello,

the aim is, a package selection without any program needed for development like 
gcc, gdb, flex, etc. I need this for an computer witch will be used only as an 
terminal for ssh, X and rdp connections. This kind of computer sometimes known 
as Thinclient. I try to disable this kind of packages in the packagemanager but 
this don't work because many dependencys are not solved. Thanks for any hind to 
reach my goal.
