No need to bootstrap it yourself unless you fetch from CVS.  The tarballs we 
release are all pre-bootstrapped with a suitable version of autoconf and 
automake.

Don't forget that the make process is recursive, so you also need to `export 
MAKE=gmake' for the submakes to be called correctly.

Perhaps there is a broken macro in autoconf or libtool with respect to ksh?  
Can you retry with bash as the CONFIG_SHELL and see if that works?

Since we eliminated ltconfig before libtool-1.4, the reconfigure is normal 
after running the bootstrap script, since bootstrapping libtool requires two 
passes through configure, the first generates the Makefile (which can then 
make ltmain.sh from ltmain.in), and the second makes the libtool script from 
ltmain.sh.

Alphabetically, COPYING and Makefile are exactly the second files in their 
respective directories, which makes me think that the quoting in the new tags 
code is not robust to the version of ksh you are running... or possibly the 
version of /bin/sh configure re-execs itself with.  If you can prove this 
somehow, we might be able to beat out a workaround for the next release.

Presuming that none of my suggestions above is the cause, it looks as though 
you have misinstalled one of the autotools...

This is what I get:

  $ wget ftp://alpha.gnu.org/gnu/libtool/libtool-1.4b.tar.gz
  ...
  $ tar zxf libtool-1.4b
  $ cd libtool-1.4b
  $ ./configure --version
  libtool configure 1.4b

And just to double check (note that the `a' suffix on the version numbers is 
because I have slightly newer than release versions built from CVS -- I hope 
that small difference isn't why you have errors though):
