I think you are missing some or all of the following, mentioned in the
file INSTALL:

  * Complex Text Layout support libraries

  Emacs needs the optional libraries "m17n-db", "libm17n-flt", "libotf"
  to correctly display such complex scripts as Indic and Khmer.
  On some systems, particularly GNU/Linux, these libraries may be
  already present or available as additional packages.  Note that if
  there is a separate `dev' or `devel' package, for use at compilation
  time rather than run time, you will need that as well as the
  corresponding run time package; typically the dev package will contain
  header files and a library archive.  Otherwise, you can download and
  build libraries from sources.

  The sources of these libraries are available by anonymous CVS from
  cvs.m17n.org.

      % cvs -d :pserver:address@hidden:/cvs/m17n login
      % cvs -d :pserver:address@hidden:/cvs/m17n co m17n-db
      % cvs -d :pserver:address@hidden:/cvs/m17n co m17n-lib
      % cvs -d :pserver:address@hidden:/cvs/m17n co libotf

  For m17n-lib, if you have problems with making the whole package
  because you lack some other packages on which m17n-lib depends, try to
  configure it with the option "--without-gui".

Handa-san, can you please tell which ones of these, if any, are needed
for Arabic shaping support?  I think at least libotf is needed, but
I'm not sure.
