gtk+ link error

[Russell Shaw <rjshaw iprimus com au>]

Hi,
I built and installed glib from cvs into /usr/local then tried building
gtk from cvs.

I verified pkg-config:
  PKG_CONFIG_PATH="/usr/local/lib/pkgconfig" pkg-config glib-2.0 --cflags --libs

gives:
  -I/usr/local/include/glib-2.0 -I/usr/local/lib/glib-2.0/include  -L/usr/local/lib -lglib-2.0

To build gtk, i did:
  ./configure CFLAGS="-g -O0" --enable-gtk-doc=yes  PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"

It gives an error:

/bin/sh ../libtool --mode=link gcc  -g -O0 -Wall   -o gtk-query-immodules-2.0  queryimmodules.o

I think it's because it first links with /usr/lib/libglib-2.0.so (my old system glib)
instead of /usr/local/lib/libglib-2.0.so (newly compiled which has g_unsetenv).

How do i get /usr/local/lib/libglib-2.0.so linked instead of /usr/lib/libglib-2.0.so ?
