 mpg123.el is not byte-compiled, so it seems right.
 On the other hand, psgml is byte-compiled by some emacsen according
 to the chosen port (psgml, psgml-emacs20, etc...) but these have
 confliction. It is not so good.

 In these cases, byte-compiled files are installed in the directory
 that are hidden from other emacsen. It seems right position since
 byte-compiled files depend on some specific emacsen.

 For now, elisp ports above have run-dependency on emacs21, so the correct behavior
 is to de-install old elisp ports at first and re-install newer elisp ports later.
 
 But I think the bad point here is that elisp ports may change destination directory
 without changing their portversion (when bsd.emacs.mk is changed while the port
 itself is not changed). I think such a change is not necessary.

 I think latter one (learn from debian emacsen-common package) is better.
 I wrote a set of installation/deinstallation scripts for elisp ports.
 I'll post it to ports@ soon.
