Can you give more details on that?  As I recall I was able to compile
the 0.61.1 sources on an AFS file system without having to mess with
peculiarities of hard links and symbolic links.  We did have to fiddle 
around with several scripts when installing S-PLUS but I don't
remember doing that with R.

For those who don't have experience with AFS, the problem stems from
an inability to create a hard link to a file in another directory.  File 
access lists in AFS are specified on a per-directory basis.  The
argument from Transarc (the AFS vendor) is that when the same file exists
simultaneously in two different directories then the user's access
rights to that file are not clearly defined.  Thus they forbid using
hard links that span directories.  We have tried to convince them that
they should just use the policy that the user's access rights are
those corresponding to the path by which they are accessing the file
but they don't seem to like that idea.
