Question re: remember to run `libtool --finish ...`

Hi.

I port/package software for AIX and often get this message during "make install"
libtool: install: warning: remember to run `libtool --finish /some/directory`

I have run the command manually, and not run it. I am unable to see what difference it is making.

Questions:

  1. What is the purpose?
  2. What is it looking for/What did it (libtool) see that it sends this warning for everything (e.g., httpd shared modules) it installs?

Note: using GNU install script, not AIX built-in.

Man Page for libtool (all Section 1) - The UNIX and Linux Forums Maybe it does some sort of strip or chmod?

   Description of finish mode:

   Complete the installation of libtool libraries.

   Each LIBDIR is a directory that contains libtool libraries.

   The  commands that this mode executes may require superuser privileges.
   Use the \`--dry-run' option if you just want to see what would  be  exe-
   cuted.
