I'm not using automake - only autoconf so I have no DESTDIR. Regardless, this
wasn't the problem.

I grabbed your tgz and started poking it. You're right - yours works. I was
totally baffled as to why b/c when I used exactly the same commands it would
still try to relink the library and fail. Finally, I copied the libtool out
of foo-0.0 and tried it in my source dir. The problems vanished.

It seems this is a bug in the newest libtool - I had checked mine out of cvs
about three days ago whereas I believe yours was 3 months old.

The new libtool will put a --rpath in the library compilation and thus need
to relink the dependent library. Try:

cd foo-0.0
copy in the newest from cvs
make clean
clear (the next command is noisy and has an error you have to search for)
make install DESTDIR=`pwd`/tmp

Truely horrifying is that libtool doesn't even stop after failing to relink
- it just continues on it's merry way. Look for the telltale error somewhere
in your scrollback history:

gcc -shared  bar.lo  -Wl,--rpath -Wl,/usr/local/lib  -L/usr/local/lib -lfoo
-Wl,-soname -Wl, -o .libs/
/usr/bin/ld: cannot find -lfoo
collect2: ld returned 1 exit status
libtool: install: error: relink `' with the above command before
installing it

Bleh. Well, by downgrading my libtool this is no longer a concern for me.
However, I'd be happy to provide any more info to help in fixing this.
