I just installed tkrplot in R 2.4.1 and it worked fine.  I've never seen 
the error you're reporting.  However, I see what looks like a typo that 
might affect some systems:

In the tkrplot .First.lib function, I see

>             path <- file.path("libs", .Platform$r_arc, dlname)
>         else path <- file.path("libs", dlname)

On the 3rd line, I think .Platform$r_arc should be .Platform$r_arch.  On 
my system I never execute that line, but if .Platform$r_arch is set on 
your system, it would likely cause problems.
