If it is just a case of the libtool version being too old (like it is  
for OSX universal builds), then you could
download the latest version of libtool, and then copy the following  
files from it into the toplevel directories
for all the exr-related libraries:

    config.guess
    config.sub
    install-sh
    ltmain.sh

This is how I'm getting everything to build correctly under OSX as  
universal binaries.
