Comment (by dliessi):

 The `texdist` script determines if a TeX distribution is usable by
 checking if `Contents/Programs/$arch/tex` exists, where `$arch` is the
 output of `uname -p`.
 So at least that symlink is needed, besides the `texbin` one.

 I could cheat and provide only the `$arch` and `texbin` symlinks: this
 would not provide the complete picture in the universal case, and it would
 provide wrong symlinks where `uname -p` does not correspond to the actual
 architecture (e.g. on my machine it outputs `i386`, while `texlive-bin`
 installs `x86_64`), but at least existing symlinks would not point to a
 different architecture family (PowerPC vs Intel).

 The ideal situation would be to provide the following symlinks, besides
 `texbin`:
 - 32-bit Intel: `i386`
 - 64-bit Intel: `i386`, `x86_64`
 - 32-bit or PowerPC: `ppc`, `powerpc`
 - universal: the correct combination of the above

 I can determine the installed architecture, if not universal, from the
 directory name in `${texlive_mactex_texdistdir}` and manually fix the
 64-bit Intel case, but this does not work for the universal case.
 Is there a simple way to determine which architectures were installed in
 the universal case?
