I need help for compiling gtk+-2.4.0

["Stefano Zanobi" <stefanoz72 hotmail com>]

Hello, I need help for compiling gtk+-2.4.0, which I need, in turn, tu build 
Ardour program.
I'll try to explain shortly:
my PC is a pentium IV, and I've installed Linux Mandrake 10.0 system.
Then I've downloaded gtk+-2.4.0.tar.bz2 package.
I explode it in a tmp directory, enter it and enter, as superuser:

./configure

which exits with:

[...]
checking for glib-2.0 >= 2.4.0    atk >= 1.0.1    pango >= 1.4.0...
Requested 'glib-2.0 >= 2.4.0' but version of GLib is 2.2.3
configure: error: Library requirements (glib-2.0 >= 2.4.0    atk >= 1.0.1    
pango >= 1.4.0) not met;
[...]

So I've downloaded glib-2.4.7.tar.bz2 package, exploded it in a tmp dir, 
superuser, and type:

./configure
make
make install

which exits with no errors. The only warning is:

libtool: install: warning: relinking `libgobject-2.0.la'
libtool: install: warning: relinking `libgmodule-2.0.la'
libtool: install: warning: relinking `libgthread-2.0.la'

So, it seems as glib-2.4.7 installation is ok, but when I get back to gtk+ 
tmp dir and try to:

./configure

gtk configure script still exits with the same error:
Requested 'glib-2.0 >= 2.4.0' but version of GLib is 2.2.3

Please, can anyone tell me what do I do wrong?

Thank you in advance!

Stefano
