No, it doesn't mean that.
"devel" means something like:	

	This is a package in DEVELopment, i.e.,
	it is known to have problems under some circumstances.

The "some circumstances"  
	- can mean that not all functions work in current
	  versions of R,

	- can mean that C / Fortran code does not properly link on some

	- can mean that the code hasn't been tested thoroughly and is huge
	  (which automatically means it has bugs  :-)

Note that the last case is certainly true  for  'lme', 'dse' and 'design'.
I think all of these three do not require 0.62 at all.

	It certainly would be useful to have a  README file in
But then I agree "devel" just means: 
	``You are on your own if you hope it works'' :-)

    Kim> I don't seem to have .Dyn.lib so that does not help.

too bad.
