  15 This is not exactly the answer you're expecting, but I prefer to do it
  16 that way:
  17
  18 - I do install the packages, but only perform a symlink installation, so
  19   nothing is really duplicated,
  20 - this also has the advantage that you can remove the symlinks you don't
  21   want (for instance if you have conflicting versions in site-packages)
  22   without affecting your copy of the repo.

  55 After poking around for awhile and conducting some experiments, I
  56 don't think XEmacs supports running the packages directly from the CVS
  57 hierarchy.  You will have to create the forest of symlinks that Didier
  58 mentioned earlier:
  59
  60 cd ~/emacs/packages/xemacs-packages
  61 mkdir lisp
  62
  63 cd lisp
  64 ln -s ../c-support
  65
  66 Repeat the final 2 steps as necessary.  If you set
  67
  68 symlink =3D t
  69
  70 in Local.rules, this may happen automatically.  I do not fully grok
  71 that mechanixm.
  72
  73 Mike Sperber - please correct me where I have published incorrect informati=
  74 on.

  86 I think Vin is right.  Alan, why don't you just modify
  87 XEMACS_INSTALLED_PACKAGES_ROOT in Local.rules to some location or
  88 other, then do `make install' from the packages directory.  Then FAQ
  89 question 2.1.1 should tell you how to configure XEmacs to find them.

 114 Actually,
 115 $ for f in ../* ; do ln -s $f ${f##*/} ; done
 116 did the job nicely.  :-)
 117
 118 And my XEmacs now starts up with its packages.  :-)  Thank you indeed!

 126
 127 I think I've got that set in my Local.rules, but because of the ((natnump
 128 -1)) problem, I couldn't get that far.
