Error with GLib while compiling Pango

[igodit]

I get this error message while compiling Pango.
How do I resolve it?

checking for GLIB - version >= 2.4.0...
*** 'pkg-config --modversion glib-2.0' returned 2.4.0, but GLIB (2.0.1)
*** was found! If pkg-config was correct, then it is best
*** to remove the old version of GLib. You may also be able to fix the error
*** by modifying your LD_LIBRARY_PATH enviroment variable, or by editing
*** /etc/ld.so.conf. Make sure you have run ldconfig if that is
*** required on your system.
*** If pkg-config was wrong, set the environment variable PKG_CONFIG_PATH
*** to point to the correct configuration files

Assuming that you have installed glib2.4.0 in the standard/default location you can try to force pango to look for the glib libraries in that location ./configure --with-glibpath=\path-to-glib or try to set the CFLAGS --> export CFLAGS="-L/path/to/glib2.4/lib -I/path/to/glib2.4/include

I did an export command in the ~/.profile

How can I make it global
