The install path may be a staging directory and the rpath could mention a 
directory that doesn't exist right now:  the rpath would need to be 
canonicalized manually... remove /dir/.. pairs, eliminate multiple or trailing 
slashes etc.  This makes it easy to canonicalize rpath immediately for storage 
in the pseudo library, rather than on every comparison.

In spite of the fact that the install directory needs to exist, for the best 
chance of a match in the face of symbolic links, it would probably be best to 
canonicalize the install path using the same algorithm.

Feel free to use a shell function, autoconf is using them now so there is no 
reason for libtool to resist.  Infact, converting ltmain.in to use shell 
functions might untangle the spaghetti somewhat!

Cheers,
        Gary.
