problem compiling gtk+-2.5.5

[DANIELLLANO <DANIELLLANO terra es>]

I'm using Debian unstable on x86
I want to compile the new gtk+-2.5.5
glib-2.5.6 compiled and installed successfully
I did:
export LDFLAGS=-L/tmp/usr/lib
export CFLAGS=-I/tmp/usr/include
export LD_LIBRARY_PATH=/tmp/usr/lib
export PKG_CONFIG_PATH=/tmp/usr/lib/pkgconfig
./configure --prefix=/tmp/usr

And gtk+-2.5.5 gets:
