I have attached it.

I get this error:

Error in CONDITIONS::CLCS-LOAD [or a callee]: "~:<address@hidden, ~_~}~:>" 
cannot be coerced to a pathname.

And at a _guess_, I would say it might have something to do with Gcl's
pathname system.??

I think the default (xp::install) does the right thing.  You don't
_have_ to call xp::install, (although Gcl needs the functions provided
by XP for conformance) and there is also an option to remove the
effects of installing.  Xpx is 'just' example code, it is certainly
not necessary for XP.  It provides an example of how to use the
pprinter to print (a subset of) Common Lisp as Pascal.
