hmmm, i was investigating this.  the cause geiser fails is that, in the
process of looking for other things, it's not able to find
`program-arities', exported by (system vm program).  i am not sure why:

~$ guile

Guile comes with ABSOLUTELY NO WARRANTY; for details type `,show w'.

Enter `,help' for help.
scheme@(guile-user)> (use-modules (system vm program))
scheme@(guile-user)> program-arity
$1 = #<procedure program-arity (prog ip)>
scheme@(guile-user)> program-arities
ERROR: Unbound variable: program-arities

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile-user) [1]> 

Any idea what might be wrong?
