The error message is puzzling; spatstat is certainly available.

However you should be getting a ***warning*** message about being
unable to ``rename'' <stuff>/spatstat.

The somewhat mysterious cause of such warnings is that it is
necessary to supply an *absolute* pathname for ``lib'' rather
than a relative pathname as you have done.  I was flummoxed by
this for decades; very recently Simon Urbanek (thank you again
Simon) pointed out to me the error of my ways.

Try something like:

xlib <- paste(getwd(),"/R/i486-pc-linux-gnu-library/2.8",sep="/")
install.packages("spatstat",dependencies=TRUE,lib=xlib)

and see how you go.
