Not being able to run your examples is not 'minor': it is the first 
test that the package is installed properly, and 'china' is the first 
example.

You haven't told us the 'at a minimum information' asked for in the 
posting guide.  What version of R (including what architecture) are 
you running?  Have you actually tried compiling from the package 
sources yourself?  It works for me on i386 and x86_64.

So there is a fair chance simply installing from the sources will work 
for you.  If you have Xcode installed, all you need to do is

install.packages('mapdata', type = 'source')
library(mapdata)
example(china)
