   Am I doing something silly, if not how can I get around

   Thanks for any help

There was an incompatible change in in-package in the CL standard.
The X3J13 committee voted in March 1989 to change the functionality of
in-package and to make it a macro.  The new definition specifies that
the argument to in-package is NOT EVALUATED.  (See Steele, CLtL 2nd
Ed., p. 263-264)

You cannot do what you want using in-package.  The closest you can get
would be to BIND the variable *package* to the value of a package
created earlier, but I think this would be a bad idea.  Why do you
want the name to be in a variable anyway?
