Nqkoj moje li da mi kaje za kakvo sluji tova pkg-cinfig ?

 Opitvam se da si instaliram glib 2.2, vsi4ko mina uj bez
 greshki, no kogato se opitam da instaliram neshto pri
./configure mi da va tazi greska:

checking if libtool supports shared libraries... yes
checking whether -lc should be explicitly linked in... no
creating libtool
checking for Win32... no
checking for aclocal flags...
checking for pkg-config... /usr/local/bin/pkg-config
checking for GLIB - version >= 2.0.0...
 *** 'pkg-config --modversion glib-2.0' returned 2.2.0, but
GLIB (2.0.6)
*** 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
no
configure: error:
*** GLIB 2.0.0 or better is required. The latest version of
*** GLIB is always available from ftp://ftp.gtk.org/.

 pkg-config se izpolzva za konfigurirane na na biblioteki.
pochti vsqka biblioteka ima takuv tool. 
 pri compilirane vmesto da ukazvash pulnite imena na libs
 (sushtoto e i za druga informaciq) pishesh pkg-config --libs
ili kvato e opciqta na tool-a.
 za versiq < 2.0 se izpolzvashe gtk-config (ili neshto takova
beshe).
 uvi ne sum 100% siguren v kakvo e problema no qvno neshto si
poumazal.
trqbva da se sasredotochish vurhu:
'pkg-config --modversion glib-2.0' returned 2.2.0, but
GLIB (2.0.6)*** was found! 
vig v kakvi sa versiite i pishi tuka.
