gtk.immodules error

Problem:
when building gtk+,  i met a gtk.immodules error, and  i try different gtk+  versions,   all the same.
gtk+ building failed:
*** [gtk.immodules] error 127....  gtk-query-immodules-2.0  >gtk.immodule  

building...

ignore the errors, keep compile and install, install failed,and system crashed.
system failed:
"init: id "x" respawning too fast: disabled for 5 minutes

Solution:
1) init 3, login with root permission. find the gtk buiding folder;
2) Check the $Gtk+-2.0/gtk/gtk-query-immodules file,  where the error happens (gtk-query-immodules  *.lo > gtk.immodules,  but after the sh run, the gtk.immodules is empty, so the problem is here.).  The file is generated by libtool,  i think its  libtool's issue,  my libtool is too old, i upgrade it, same error;
3) find lt-gtk-query-immodules-2.0/gtk-query-immodules-2.0 cannot run;
4) grep -r gtk-query-immodules . , find the Makefile for gtk-query-immodules-2.0, or delete it and module/input/im*.lo (1 im*.lo is enough).
5) After gtk-query-immodules rebuild, you'll see the compile statement(or you can check the Makefile in the same folder), record the statements;
6) Write a helloworld program with the libs above linked, execute it, if cannot run, remove libs one by one until success, then you'll spot the broke library. In my computer, the pixman-1 library broken, it's all ok after reinstall.
