I configured and installed glib 2.0.6 with --prefix=/usr. Now when I try to configure atk (with --prefix=/usr) and pango (with --prefix=/usr), I get the following error:

checking for GLIB - version >= 2.0.0... no
*** Could not run GLIB test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GLIB is incorrectly installed.
configure: error:
