annoying _gdk_imlib_data in libgnomeui / bad path for libgdk_imlib

[Bertrand Guiheneuf <Bertrand Guiheneuf inria fr>]

Since yesterday, 
control-center, gmc and other refuse to run. Example:
gmc: error in loading shared libraries
/opt/GNOME/lib/libgnomeui.so.0: undefined symbol: _gdk_imlib_data

here is what my ldconfig -v gives:
/opt/GNOME/lib:
        libgdk_imlib.so.1 => libgdk_imlib.so.1.8.1

/usr/lib:
        libgdk_imlib.so.1 => libgdk_imlib.so.1.8.0

1.8.1 --> with    _gdk_imlib_data
1.8.0 --> without _gdk_imlib_data


well, I do not know why, but when stracing gmc, I see it links against
the version in /usr/lib not /opt/GNOME/lib
(my LD_LIBRARY_PATH is void btw)

Well, here is gmc link line:
=========
gcc  -rdynamic -L/opt/GNOME/lib -L/usr/X11/lib -rdynamic -lgnomeui -lart_lgpl 
-L/opt/GNOME/lib -lgdk_imlib -ljpeg -ltiff -lgif -lpng -lz -lSM -lICE -lgtk 
-lgdk -lgmodule -lXext -lX11 -lgnome -lgnomesupport -lesd -lm -laudiofile -ldb 
-lglib -ldl -o gmc main.o mad.o dlg.o screen.o widget.o wtools.o info.o 
boxes.o file.o find.o dialog.o key.o chmod.o chown.o view.o panelize.o 
hotlist.o background.o dir.o util.o win.o color.o profile.o user.o ext.o 
setup.o subshell.o terms.o achown.o fsusage.o mountlist.o regex.o complete.o 
command.o option.o cmd.o utilunix.o xslint.o gdialogs.o filenot.o  gblist.o 
gcache.o gcliplabel.o gcmd.o gdesktop-icon.o gdesktop.o gdnd.o ghelp.o gicon.o 
ginfo.o gkey.o glayout.o gmain.o gmc-chargrid.o gmenu.o gmetadata.o 
gpageprop.o gpopup.o gprop.o gscreen.o gtools.o gtree.o gutil.o gview.o 
gtkdtree.o gwidget.o -L../vfs -L../slang -L../gtkedit -lvfs-mc -lgtkedit  
-L/opt/GNOME/lib  -lglib
======

if I just add an  -Wl,--rpath /opt/GNOME/lib just before the -lgnomeui,
all goes well. (well at least gmc runs, though if strangely show two 
vscrollbars on the left, but if don't have this _gdk_imlib_data undefined)


Could someone please explain me why ldconfig takes the file in /usr/lib
and as I need the old gdk_imlib library for wmaker, what should be done 
to avoid those problems.

Thanks in advance.


	Bertrand.
