lack of "info pretty-printer" in gdb 7.2 and 7.7

Dear Community,

I would like to use pretty printer feature during debugging.
I built the programs gdb 7.2 and gdb 7.7.

My problem is the following: when I call "help info" command, there is
a lack of "info pretty-printer" in the output of previous command.

This is the output of "apropos pretty":
(gdb) apropos pretty
set print array -- Set pretty formatting of arrays
set print pretty -- Set pretty formatting of structures
set print raw frame-arguments -- Set whether to print frame arguments
in raw form
show print array -- Show pretty formatting of arrays
show print pretty -- Show pretty formatting of structures
show print raw frame-arguments -- Show whether to print frame
arguments in raw form

My build command was the following:
"/configure --prefix=/usr --with-python && make"
My system is:
Linux _myhostname_ 2.6.27.54-0.2-default #1 SMP 2010-10-19 18:40:07
+0200 x86_64 x86_64 x86_64 GNU/Linux

On the basis of this page:
http://lumiera.org/documentation/technical/howto/DebugGdbPretty.html
I checked out the stlPrettyPrinter and updated my .gdbinit file as well.

In gdb, there is python support:
(gdb) python print(123)
123

Could you help me to be able to use this feature in gdb?
I am waiting for your reply!

BR,
Steve
