The _realcommand() function in the bash_completion script sniffs for readlink(1) and then uses 'readlink -f' to resolve symlinks. However, this is not portable; the readlink shipping with at least Mac OS X (and I would imagine some of BSDs) does not have the '-f' option. AFAIK it isn't possible to use this readlink to resolve multiple levels of symlinks.

Not a complete fix for the problem, but greadlink might save the day in some cases.
