You should have received the following error message:

 ERROR: --prefix not allowed for a Mac OS X build, unless either
          --enable-xonx is supplied (to create a Unix-style
            build), or 
          --enable-macprefix is supplied (to allow a Mac-style
            installation, even though --prefix is normally used
            for Unix-style installations)

So, you want `--enable-macprefix'.

We disabled `--prefix' by default on Mac OS X, because it doesn't quite
produce the layout that a Unix user would expect. The `--enable-macprefix'
flag lets you use `--prefix' anyway.
