I am trying to construct cross compiler for NEC V850( OS: kubuntu 8.10).
 I was doing well until I tried to "make install".
I got the error message like below:

--------------------------------------------------------------------------------
libtool: install: v850-elf-ranlib 
/usr/local/v850-gcc/v850-elf/lib/libsupc++.a
../libtool: line 795: v850-elf-ranlib: command not found

I found similar help in help-archive.
http://lists.gnu.org/archive/html/help-make/2001-12/msg00009.html

So, I follow the advices(run the command) like below:

env PATH=.:$PATH make install

No Error this time. Seems fine. But I see another messages like below:

--------------------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/v850-gcc/v850-elf/lib

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_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.
--------------------------------------------------------------------------------

I have no idea what "make install" is doing. 
Could somebody please tell me the reason of the error and why set the 
environment path as above can avoid the error.

Anyway, there is alternative way to avoid the error(without setting 
environment path):
I know where the command "v850-elf-ranlib" is located. So I copy it to 
usr/local/bin and "make install". Though also got the same message as 
above.

So, I guess these two ways are doing the almost the same thing... am I 
wrong?
