gthumb编译后不能正常运行？

gthumb2.7.4
Compiling
=========

  In order to build this program you need a working GNOME environment
  version 2 or greater, with the development tools installed properly.  
  The following is the detailed list of libraries you need:

    * glib             version >= 2.2.0
    * gtk             version >= 2.2.0
    * libxml         version >= 2.4.0
    * libgnome         version >= 2.2.0
    * libgnomeui         version >= 2.2.0
    * libgnomecanvas     version >= 2.0.0
    * gnome-vfs         version >= 2.1.3
    * libglade         version >= 2.0.0
    * libgnomeprint     version >= 2.1.0
    * libgnomeprintui     version >= 2.1.0
    * libbonobo         version >= 2.3.3
    * libbonoboui         version >= 2.3.3

按照上面说的，装了包之后。
编译安装，./configure --prefix=/usr && make && make check && su && make install，出现以下错误：
root@LFS:/home/cyx/gthumb-2.7.4# make install

先不管，运行gthumb
cyx@LFS:~$ gthumb

(gthumb:3378): Gtk-WARNING **: Error loading icon from file '/usr/share/pixmaps/ gthumb.png':
        无法打开文件“/usr/share/pixmaps/gthumb.png”：没有那个文件或目录

(gthumb:3378): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed
出现gthumb图形界面，但不能打开任何图片(见附件快照）


现在有几个问题要问：

1.我按照LFS和BLFS说明，每个包都是装在/usr下的，照理说应该不会有什么因为库文件或头文件找不到，导致程序编译或运行出错的机会。但是在编译安装一些包的时候，往往会出现像这样的信息：
[color="Red"]Libraries have been installed in:
   /usr/lib/gthumb

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

是不是我应该在/etc/ld.so.conf里加进去/usr/lib/gthumb，并ldconfig后，程序才能正常运行？

2.如果上面的理论成立，我也在/etc/ld.so.conf里加了/usr/lib/gthumb，程序还是不能运行，那该从哪里检查出错原因？考虑到在安装gthumb前，我先安装了它的依赖包（文章可见具体包的名字），在编译这些包是，也出现过问题1中描述的情况，是不是也需要按照每个包提供的信息，在/etc/ld.so.conf里加入他们的文件搜索路径？我现在是没有加入他们的搜索路径，是否这才是gthumb不能运行的原因？

问题3：
root用户运行make install时参照Makeflie文件的，应该在Makefile里有install字段，我贴出来：
check-am: all-am
check: check-recursive
all-am: Makefile config.h
installdirs: installdirs-recursive
installdirs-am:

[color="Red"]install: install-recursive
install-exec: install-exec-recursive
install-data: install-data-recursive
uninstall: uninstall-recursive
可以看出，install是引用install-recursive字段的，但我在Makefile里找不到相关的字段名。那么make install到底是怎么运行的，到底做了些什么事情？附上Makefile文件。请大家帮忙解决一下。
